Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 × ×
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 × ×
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 × + 15C5 ×
P = ( 15C8 + 15C5 )
P = ( ( ) + ( ) )
P = ( 6435 + 3003 )
P = ( 9438)
P = ( 4719)
P =
P = 0.29

=========================================================
Explanation:
To convert from a percent to a decimal, move the decimal point over 2 spots to the left
25% = 25.0% converts to 0.25
Think of 0.3 as 0.30
Comparing 0.25 and 0.30, we see that 0.25 is smaller. This is because 25 is smaller than 30.
---------------------
Put another way:
0.3 = 0.30 = 30%
We can see that 25% is smaller than 30%
---------------------
Whichever method you prefer, 25% is smaller than 0.3
