Suppose that the probability of giving birth to a boy and the probability of giving birth to a girl are both 0.5. Find the proba
seropon [69]

Answer:

a.0.0078125

b. 0.1640625

c. 0.0078125

d. 0.0078125

Step-by-step explanation:

To solve this question we can use the binomial probability function:

Prob(k\,successes\,in\,n\,trials)=\left(\begin{array}{c}n&k\end{array}\right) p^k q^{(n-k)}\\

where

  • n is the number of trials in this case the number of children
  • k is the number of successes, we can think it as the number of boys
  • p is the probability that is a boy
  • q is the probability that is a girl,

In this case case p=q

Then

(a) Prob(B,B,B,B,B,B,B)=1\times0.5^7

(b) Prob(5\,boys\,in\,7\,children)=\left(\begin{array}{c}7&5\end{array}\right)0.5^7

(c)Prob(G\,last\,and\,6\,boys)=Prob(B)^6Prob(G)=0.5^7

(d) Prob(G\,first\,and\,6\,boys)=Prob(G)Prob(B)^6=0.5^7

(a), (c) and (d) are equal as a result of equal probability of giving birth to a boy or a girl. (b) is different because it takes into account the different orders that births can occur
