The probability that the result is a multiple of
2 and a multiple of 5 is; 0.1
We are told that:
-The spinner has 10 equal areas
- Numbers on the spinner are 1 to 10
Thus,
Total available numbers; N = 10 numbers
We want to find the probability that the result
is a multiple of both 2 and 5.
Now,among all the digits from 1 to 10, the
only one that is a multiple of both 2 and 5 is
10.
Thus,
P(result is a multiple of 2 and a multiple of 5)
= 1/10 = 0.1
The 3rd equation, as if you solve for x as shown, you will end up with equation x=8.
Answer:
46.3%/100 x 162 = 75.006 games. I guess you could round it off to 75 games
