Anais bought 4 1/2 yards of ribbon. she had 3 feet 8 inches of ribbon left after trimming some curtains. how many inches of ribbon did anais use to trim the curtains?

She used 118 inches of ribbon.

Step-by-step explanation:

Convert the yards to inches.

4.5 yards= 162 inches.

Convert feet to inches.

3 feet= 36 inches.

She has 44 inches of ribbon left.

Now you subtract.

162-44= 118

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
