A bag has 3 candies: strawberry, lemon and mint. One is picked at random. What is the probability of picking a strawberry candy?
The sample space of candies in the bag is: S = {strawberry, lemon, mint} Total number of possible outcomes = 3. The event E consists of picking a strawberry candy: E = {strawberry} Number of favourable outcomes = 1. Using the formula for theoretical probability: P(E) = Number of favourable outcomesRead more
The sample space of candies in the bag is:
S = {strawberry, lemon, mint}
Total number of possible outcomes = 3.
The event E consists of picking a strawberry candy:
E = {strawberry}
Number of favourable outcomes = 1.
Using the formula for theoretical probability:
P(E) = Number of favourable outcomes / Total possible outcomes
P(strawberry candy) = 1 / 3 (which is approximately 0.333 or 33.3%).
Hence, the probability is 1 / 3.

(iii) Rolling a fair 6-sided die. (iv) Choosing a marble randomly from a bag that contains 3 red marbles and 7 blue marbles. (v) A baby is born. It is a boy or a girl.
(i) Not equally likely: A normal working car usually starts, depending on mechanical condition rather than pure chance. (ii) Equally likely: A fair coin is balanced, giving heads and tails an equal chance of 1/2 each. (iii) Equally likely: A fair 6-sided die gives each number from 1 to 6 an identicaRead more

(iii) Equally likely: A fair 6-sided die gives each number from 1 to 6 an identical probability of 1/6.
(iv) Not equally likely: Blue marbles (7) outnumber red marbles (3), making blue more likely.
(v) Equally likely: Biologically, a newborn being a boy or a girl is equally likely with probability 1/2.

The blank for the concept is filled by 'relative frequency'. The blank for the value is filled by '15/50' (or '3/10' or '0.3').

The blank for the concept is filled by ‘relative frequency’.
The blank for the value is filled by ’15/50′ (or ‘3/10’ or ‘0.3’).
Reason: The count 15 represents the frequency (the actual number of times students chose football). The ratio of this frequency to the total sample size of 50 students defines the relative frequency:
Relative frequency = 15 / 50 = 3 / 10 = 0.3 (or 30%).

Let the radius of the circle be r cm. Given circumference = 44 cm. The formula for the perimeter of a circle is: Circumference = 2 x π x r Substitute π = 22/7: 44 = 2 x (22/7) x r 44 = (44/7) x r Multiply both sides by 7 and divide by 44: r = (44 x 7) / 44 r = 7 cm. Therefore, the radius of the circRead more
Let the radius of the circle be r cm.
Given circumference = 44 cm.
The formula for the perimeter of a circle is: Circumference = 2 x π x r
Substitute π = 22/7: 44 = 2 x (22/7) x r 44 = (44/7) x r
Multiply both sides by 7 and divide by 44: r = (44 x 7) / 44 r = 7 cm.
Therefore, the radius of the circle is 7 cm.
