Nadya [2.5K]
6 ft= 6x12in= 72 in.
8 ft= 8x12in= 96 in.
12ft=12x12in=144 in
25ft=25x12in=300 in
50ft=50x12in=600 in

72 in, 96 in, 96 in, 144 in, 300 in, 300 in, 600 in
Mean= (72+96+96+144+300+300+600)÷7
1608÷7 = 229.7 inches
Median=middle value in set = 144 inches
Mode= value(s) tha occur most often = 96 inches and 300 inches
Range=difference of largest and smallest values in set = 600-72= 528

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}
