Answer:
D
Step-by-step explanation:
To find the probability of not having twins, we can subtract the probability of having twins from 1. This is because probabilities always add up to 1.
1 - 0.015 = 0.985
The probability of not having twins is 0.985.

Answer:
0.8
Step-by-step explanation:
9(0.5y+0.4)=590.1y+1.3)+0.3
4.5y+3.6=0.5y+6.5+0.3
4.5y+3.6=0.5y+6.8
4.5y-0.5y=6.8-3.6
4y=3.2
y=0.8
