Answer:
1/5
Step-by-step explanation:
Since the surveys are chosen with replacement (the first one is replaced before the second is chosen), the events are independent. This means that the probability of both together is the product of each event's probability.
The probability of choosing a survey that indicates 4 children in the family is 8/60, since there are 8 surveys with 4 children out of a total of (9+18+22+8+3) = 60 surveys.
The probability of choosing a survey that indicates 1 child is 9/60, since there are 9 surveys with 1 child out of a total of 60.
Together this gives us
8/60(9/60) = 72/360 = 1/5
Answer:
When subtracts fractions with the same denominator, you only have to subtract the numerator.
5/9-3/9=
The denominators are the same, you just have to subtract the denominator. So in this case, you would only need to subtract 5-3. Therefore the answer would be 2/9. (Simplify if needed.)
