The number of favorable outcome (boy-girl)=1

Now, the probability that she will have boy-girl is given by :-

Hence, the probability that she will have boy-girl is 0.25.

Given: The total number of outcomes ( boy-boy, girl-girl, girl-boy, and boy-girl.)= 4

The number of favorable outcome (boy-girl)=1

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
