When a customer places an order at Derin's bakery, there is an 85% probability that the order will include some kind of dessert.

Lelu [443]

Answer:

0.68

Step-by-step explanation:

The probability that the order will include some kind of dessert is $p=0.85$ and the probability that the order will not include some kind of dessert is $q=1-p=1-0.85=0.15.$

First, find the probability that all 7 orders include some kind of dessert:

$Pr_1=C_7^7p^7q^{7-7}=p^7=(0.85)^7.$

Then the probability that at least order will not include dessert is

$Pr_2=1-Pr_1=1-(0.85)^7\approx 0.68$

Can you help me solve y=-3x-2 (-7x-6y=-10

navik [9.2K]

$y=-3x-2\\-7x-6y=-10\\\\
-7x-6(-3x-2)=-10\\
-7x+18x+12=-10\\
11x=-22\\
x=-2\\\\y=-3\cdot(-2)-2\\y=6-2\\y=4$
