Question

Select the correct answer.

Jenson has a basket containing oranges, apples, and pears. He picks a piece of fruit from the basket 40 times, replacing the fruit before each draw. From these 40 trials, Jenson estimates that the probability of picking an orange is 0.25, the probability of picking an apple is 0.3, and the probability of picking a pear is 0.45. How many times did Jenson pick an apple during the 40 trials?

A.
10

B.
12

C.
15

D.
18

Answer 1

Answer: B. 12

Step-by-step explanation: Expected no. = No. of trials × p

= 40 × 0.3

= 12

Answer 2

B. 12

Explanation:

Experimental probability is calculated by dividing the number of times an event happens by the total number of trials in an actual experiment.

`\textsf{Experimental Probability} = \frac{\textsf{Number of times an event happens}}{\textsf{Total number of trials}}`

Given information:

• Experimental probability of picking an apple = 0.3
• Total number of trials = 40

Substitute the given values into the formula:

`\implies \sf 0.3=\frac{\textsf{Number of times Jenson picked an apple}}{40}`

`\implies \sf \textsf{Number of times Jenson picked an apple}=0.3 * 40=12`

Therefore, Jenson picked an apple 12 times during the 40 trials.
