Answer:0.625
Step-by-step explanation:
Given
There are two coins one is fair and another is bent
Probability of getting a head on fair coin is 0.5
Probability of getting a head on bent coin is 0.75
If both coins are tossed once
probability of getting at least one of the coin will come up tails is




We know that speed * time = distance
Before we start we need to make sure the units for all three numbers are right
The time is 1/3 of a hour, 1/3*60 = 20 minutes
x * 20 = 22.5
x *2 * 10 = 22.5
2x = 2.25
x = 1.125
The sum of a polygon's angles are 540.
When you add all the angles together here, you get 456.
Now subtract 456 from 540.
540 - 456 = 84
