Answer:
The probabilities are 3/8, 1/8 and 3/8 respectively
Step-by-step explanation:
The sample space for the provided case can be written as:
S= {(bbb, bbg, bgb, bgg, gbb, gbg, ggb, ggg)}
Here, boy child is denoted by "b" and girl child by "g".
Total number of outcomes are 8.
Number of outcomes that show exactly boys = 3.
Number of outcomes that show exactly 3 boys = 1
Number of outcomes that show exactly 1 boy = 3.
Thus, the required probabilities can be calculated as:
(a)
(b)
(c)
Thus, the required probabilities are 3/8, 1/8 and 3/8 respectively.
