1 answer:

3 0

P(A) = 0.3
P(B) = 0.5
P(A and B) = 0.3 × 0.5
P(A and B) = 0.15

P(A) = x
P(B) = 0.9
P(A and B) = x · 0.9
0.45 = 0.9x
0.9 0.9
0.5 = x
P(A) = 0.5

Answer:

17/12 or 1 and 5/12.

Step-by-step explanation:

3/4 and 2/3 needs to have the same denomenator. So, what number does both 4 and 3 go into? 12. So, 4x3=12, so we multiply the numerator by 3 too, to get 9 --> 9/12. Then, we see that 4x3=12 for 3 too so we multiply 2 by 4 which gets us 8 --> 8/12. So, now we add 9/12 + 8/12 to get 17/12, which then we make into a mixed number to get 1 and 5/12.
