Answer with explanation:</h2>
Given : The number of children a family plans to have = 7
If the boys and girls are equally likely, then the probability of getting a girl = probability of getting boy =
Now, the probability that there will be at least one girl will be:-
P(atleast one girl) = 1- P(all boys)
Hence, the probability that there will be at least one girl = 0.9921875
Since ,0.9921875 > 0.5
It means the event is likely to happen. [∵Any event E is likely to happen if P(E)>0.5]
Therefore, the probability is high enough for the couple to be very confident that they will get at least one girl in 7 children.
Answer:
7 and 6
Step-by-step explanation:
First, set up your equation.
_(x+4)_ = 7
2
multiply both sides by 2 to cross out the 2 on the bottom
_(x+4)_ *2 = 7*2
2
x+4 =14
subtract 4 from both sides
x+4= 14
-4 -4
x=10
