Answer:
3/8, 1/8, 1/2.
Explanation:
Probability may be defined as the chance of the occurring of a particular event.
The probability of a girl and a boy is 1/2.
The group of three siblings means there sample size could be
BBB, BGB, BBG, GBB, GGG, GBG, GGB, BGG. ( B = boy and G = girl).
Probability = No. of possible outcome / total outcome.
The probability of exactly two boys = BGB, BBG, GBB = 3/8.
The probability of exactly three boys = BBB = 1/8.
The probability of two boys = BBB, BGB, BBG, GBB = 4/8 = 1/2.
Thus, the correct answer is option (b).
