Answer:
24/35, about 69%
Step-by-step explanation:
The data given can be put into a 2-way table (attached). It shows that 0.48 of all calls were answered and resulted in a mortgage application. Altogether, 0.70 of all calls resulted in a mortgage application. Thus the conditional probability of interest is ...
p(spoke to attendant | applied for a mortgage) = p(spoke & applied)/p(applied)
= 0.48/0.70 = 24/35 ≈ 69%

Answer:
The probability that at least one of the children get the disease from their mother is P=0.7125.
Step-by-step explanation:
This can be modeled as a binomial random variable.
The parameter p=0.34 is the probability of a child being infected, and is constant and independent of the other events.
The parameter n=3 is the number of children (sample size).
Then, we have to calculate the probabilty that at least one of the children get the disease from their mother. That is:
The probability of exactly k children being infected can be calculated as:
Then, the easiest way to calculate this probability is using the complement: the value of the probability is 1 (or 100%) less the probability that no children gets infected.
