First, add the tenths together. 0.5+0.2=0.7
Then, add the hundredths together. 0.01+0.08=0.09
Now, add these two numbers together to get your final answer. 0.7+0.09=0.79
You need to use the binomial probability formula:
where:
n = total number of events = 10
k = number of events we are testing = 6
p = probability of event happening = 0.5
= 210×0.015625×0.0625
= 0.205078
Hence, the probability of getting 6 boys out of 10 births is
p = 0.205.
a. 11
b. 48
c. 27
