10. The probability of buying pizza for dinner is 34% and the probability of buying
kipiarov [429]

Answer:

The probability of eating pizza given that a new car is bought is 0.952

Step-by-step explanation:

This kind of problem can be solved using Baye’s theorem of conditional probability.

Let A be the event of eating pizza( same as buying pizza)

while B is the event of buying a new car

P(A) = 34% = 0.34

P(B) = 15% = 15/100 = 0.15

P(B|A) = 42% = 0.42

P(B|A) = P(BnA)/P(A)

0.42 = P(BnA)/0.34

P(B n A) = 0.34 * 0.42 = 0.1428

Now, we want to calculate P(A|B)

Mathematically;

P(A|B = P(A n B)/P(B)

Kindly know that P(A n B) = P(B n A) = 0.1428

So P(A|B) = 0.1428/0.15

P(A|B) = 0.952

Determine the value of y in the proportion 6y−10/5+7y =12 .
ira [324]

its none of them? 6y - 10/5 +7y = 12     10 divided by 5 equals 2

it will now look like this: 6y - 2 + 7y = 12

then your going to want to add 2 to both sides of the equation.

it will now look like this: 6y -2 + 7y + 2 = 12 + 2 = 14

simplify: 6y + 7y = 14

add the like terms: 13y = 14
