Answer:

$59.4

Step-by-step explanation:

Using the discrete probability outputs given in the attached table ; the probability values of having exactly 6 ; and  having 6 or more  girls are :

  • P(X = 6) = 0.111

  • P(X ≥ 6) = 0.1

<u>The </u><u>probability</u><u> of having </u><u>exactly 6 girls</u><u> can be defined as</u> :

  • P(X = 6) = 0.111 (from the discrete probability table)

2.)

<u>The </u><u>probability</u><u> of having </u><u>6 or more</u><u> girls can be defined as</u> :

  • P(X ≥ 6) =  P(X = 6) + P(X = 7) + P(X = 8)

  • From the table attached :

  • P(X ≥ 6) = 0.111 + 0.014 + 0.003 = 0.1

Therefore, the probability of having exactly 6 girls is 0.111 while the probability of having 6 or more girls is 0.1
