The expected value = Number of offspring multiplied by its

respective probability.

Expected Value:

31% chance of 0 offspring= 0.31 x 0 = 0

21% chance of 1 offspring= 0.21 x1 = 0.21

19% chance of 2 offspring = 0.19 x 2 = 0.38

17% chance of 3 offspring = 0.17 x 3 = 0.51

12% chance of 4 offspring = 0.12 of 4 = 0.48

Therefore, the expected value = 0 + 0.21 + 0.38 + 0.51 + 0.48

= 1.58 >>> answer
