When you say "I want to make sure that I solved them correctly,
the tasteful, less suspicious thing to do is to list YOUR solutions,
so that the responder can either say "that one's correct" or else
show you how to do it.

1). HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
a). The probability of each one is 1/8 = 12.5% .
b). There's only one of those on the list. 12.5%
c). 12.5%
d). There are 3 ways that can happen. 3/8 = 0.375 = 37.5%

2). There are 16 possible outcomes.
a). Prob of each outcome is 1/16 = 0.0625 = 6.25% .
b). There's only 1 way that can happen, so it's 6.25% .
c). There's only 1 way that can happen, so it's 6.25% .
d). There are 6 ways that can happen. Prob = 6/16 = 37.5%
e). There are 4 ways that can happen. Prob = 4/16 = 25%

How do you solve 1/3 of 3/4 of a fraction

Trava [24]

1 1/12

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(1/3, 3/4) = 12

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(13×44)+(34×33)=?

Complete the multiplication and the equation becomes

4/12+9/12=?

The two fractions now have like denominators so you can add the numerators.

Then:

4+9/12=13/12

This fraction cannot be reduced.

The fraction

13/12

is the same as

13÷12
