The probability of the couple having four unaffected and one affected child if both parents are carriers will be A. 0.40.

<h3>How to calculate the probability?</h3>

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Unaffected = ¾; affected = ¼

The probability of this couple having four unaffected (either HbAHbA or HbAHbS ) and one affected = n!/a!b! (s^a) (t^b)

n= Total no. of progeny = 5

a = No. of unaffected = 4

b = No. of affected = 1

s = probability of unaffected = 3/4

t = probability of affected = 1/4

Therefore, the probability of the couple having four unaffected and one affected child if both parents are carriers will be:.

= 5! / 4!1! (3/4^4) (1/4^1)

= 120/24 (0.32) (0.25)

= 0.4 = 40%

Therefore, the probability is 0.4.
