Miss english marshall has 42 yards of ribbon to make wreaths each wreath requires 8 yards of ribbon how many yards will she have left

She will have left with 2 yards.

Step-by-step explanation:

Given:

Miss English Marshall has 42 yards of ribbon to make wreaths.

Each wreath requires 8 yards of ribbon.

Now, to find the yards she have left.

Number of yards of ribbon = 42 yards.

Number of yards requires for each wreath = 8 yards.

So, to get the yards she left:

Number of yards of ribbon ÷ Number of yards requires for each wreath

.

As, by dividing 42 by 8, 2 is the remainder left.

Thus, 40 yards of ribbon is used in making 5 wreaths. And 2 yards of ribbon will be left.

Therefore, she will have left with 2 yards.

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
