Answer:
.95
Step-by-step explanation:
Using pythagorean theroem to calculate the missing side it's 35
35/37 = .94594597
or sin of angle a 71.07536 = .94594597
Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points

and

is

So the midpoint of your segment is

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.
Answer is P=3.5 or p=7/2
They are both correct
7 brown, 3 yellow, 8 red...total of 18 cards
there are 15 cards not yellow and a total of 18 cards....so the probability of not picking a yellow card is : 15/18 rounds to 5/6
