If a couple plans to have 6 ​children, what is the probability that there will be at least one boy​? Assume boys and girls are equally likely. Is that probability high enough for the couple to be very confident that they will get at least one boy in 6 ​children?

Respuesta :

Answer:

a) [tex]\frac{63}{64}[/tex]

b) The probability for the couple to be very confident that they will get at least one boy in 6 ​children is [tex]98.43[/tex]%

Step-by-step explanation:

The probability of having a boy or girl is [tex]0.5[/tex]

A couple plans to have 6 children

Probability of having at least one male child

[tex]1- (0.5)^6\\[/tex]

On solving the above term, we get -

[tex]1- (\frac{1}{2})^6\\= 1-\frac{1}{64}\\ = \frac{63}{64}[/tex]

The probability for the couple to be very confident that they will get at least one boy in 6 ​children is

[tex]\frac{63}{64}* 100\\ = 98.43[/tex]

Thus, the probability is very high
