Answer:
14/15
Step-by-step explanation:
This is because 8/15 and since you need to find the least common factor which is 15, multiply 3 times 5 and 3 times 2 which is 6/15 and 8/15+6/15=14/15
790-175x4=
take 175 and multiply it by 4 which gives you 700
Then subtract 700 from 790 and you get $90 after 4 years.
Your variables are 175 and 4
Answer:
0.9959 = 99.59% probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Tested negative
Event B: Does not carry an abdornal CF gene.
Probability of a negative test:
10% of 1/25 = 0.04 = 4%
100% of 100 - 4 = 96%. So

Negative test and not carrying an abdornal gene:
100% of 96%. So

Compute the probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.

0.9959 = 99.59% probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.
Hey, so u have to do 1/5 times 3/1 which is 3/5 and she has to read 2/5 more
