Can You Find The Expected Value For The Random Variable?

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
