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.
Hope this helps!! :)
Answer:
2 3/5 x 3 1/3 = 26/3 = 8 2/3
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
so
For m> 0, b<0
the solution in the attached figure
Let us consider the initial position of train A,
. This implies that
.
Moreover, we have

This implies that the two equations are

The two trains meet if and only if their positions are the same, at the same time:

So, the two trains meet after 2 hours.
