7p³ + 2m³ - 6m³ + 4p - 9p + 6p³
= 13p³ - 4m³ - 5p
= -4m³ + 13p³ - 5p
answer
d) -4m³ + 13p³ - 5p
The reason why the sum of your probabilities equals 0.5 is because you're only considering half of the problem--i.e. the probabilities for only one gender. For example, the probability that there are only three children and all are boys is 1/8. But, remember, it could be the case that there are three children and all are girls. Thus, the probability that there are three children is 1/4--not 1/8. Thus, multiply your result for P(X=4) and P(X=5) by 2 and you should end up with the right answer...
Answer:
c=4
Step-by-step explanation:
subtract 50-18= 32
then subtract 12c-4c= 8c
8c=32
divide 8c by 32 which gives you
c=4
