Answer:
$3.00
Step-by-step explanation:
Setting up an equation with a variable and using key words from the problem will allow you to solve for the sum of money.
'x' = sum money
'nine tenths of a sum' =
'is 2.70': = 2.70
=2.70
Multiply both sides by the reciprocal of 9/10 (10/9):
(10/9)(9/10)x = 2.70(10/9)
x = 27/9 = $3.00
Answer: The required probability is 0.32.
Step-by-step explanation:
Since we have given that
Probability of winning team A over B = 0.7
Probability of losing team A over B = 0.3
Number of matches = 7"
So, using the "Binomial distribution" :
We get that
Hence, the required probability is 0.32.
