So we can aproximate this to a whole number so:
1, 3 not really any explanation
Answer:
Mean = 3.9
Step-by-step explanation:
Given
The above table
Required
Determine the mean
The mean is calculated as thus:
Mean = Summation of x * P(x)
So, we have:
Mean = 1 * 0.14 + 2 * 0.16 + 3 * 0.12 + 4 * 0.14 + 5 * 0.13 + 6 * 0.31
Mean = 0.14 + 0.32 + 0.36 + 0.56 + 0.65 + 1.86
Mean = 3.89
Mean = 3.9 (approximated)
100 minus 75 would be 25%
Turn 25% into a decimal and you would get .25
Then multiply that by 15 and you would get $3.75
$15.00 minus $3.75 you would get $11.25
The basketball would cost $11.25.
Hope this helps!
