Use the equation P(A or B)= P(B)-P(A and B) to find the missing value below.
Anvisha [2.4K]

Answer:

P(B) = \frac{7}{8}

Step-by-step explanation:

Given

P(A or B)= P(B)-P(A and B)

P(A)=1/3

P(A and B)=1/8

P(A or B)= 3/4

Required

Find P(B)

To find P(B), all we need to do is to substitute values of P(A or B) and P(A and B) in the given equation.

This goes thus;

P(A or B) = P(B) - P(A and B) becomes

\frac{3}{4} = P(B) - \frac{1}{8}

Make P(B) the subject of formula

P(B) = \frac{3}{4} + \frac{1}{8}

Take L.C.M

P(B) = \frac{6 + 1}{8}

Add fractions

P(B) = \frac{7}{8}

From the workings above, the value of P(B) using the given equation is \frac{7}{8}

A cereal bar contains 2,000 milligrams of protein. How much protein does it contain in grams?
kolbaska11 [484]

milli = 1/1000, so milligams = 1/1000 of a gram.

So:

2000 milligrams * 1 gram/1000 milligrams = 2 grams.
