Kieran mother gets a restaurant bill for $25 he has a coupon for 15% of the acid Discount Supply she had 20% as tip what is the total after the discount and tipis how show your reasoning ​

$8.75

Step-by-step explanation:

Given data

Bill= $25

Coupon Discount=15%

Tip= 20%

Let us first find 15% of the $25

=15/100*25

=0.15*25

=$3.75

Let us first find 20% of the $25

=20/100*25

=0.20*25

=$5

Hence the coupon and the tip combined is

=3.75+5

=$8.75

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
