Question

Q6) Calculate the Expected number of candies for a randomly selected child Below are the probabilities of count of candies for children (ignoring the nature of the child-Generalized view) CHILD Candies count Probability A 1 0.015 B 4 0.20 C 3 0.65 D 5 0.005 E 6 0.01 F 2 0.120 Child A – probability of having 1 candy = 0.015. Child B – probability of having 4 candies = 0.20

Answer 1

Answer:

Expected number of candies for a randomly selected child  = 3.09

Step-by-step explanation:

Expected number of candies for a randomly selected child

=  1 * 0.015  + 4*0.20  + 3 *0.65  + 5*0.005  + 6 *0.01  + 2 * 0.12

= 0.015 + 0.8  + 1.95 + 0.025 + 0.06 + 0.24

=       3.090

=  3.09

Expected number of candies for a randomly selected child  = 3.09
