2.86%

Step-by-step explanation:

assuming there is no replacement

There is a total of 6 envelopes

Since the question is asking for red, then green, then red, order is very important

The probability of a red is 3/7

Since we have selected 1 envelope, there are only 6 total envelopes left so the probability of a green is 1/6

Then we need a red again

Since we have selected 2 envelopes, one of which is red, there are only 5 total envelopes and 2 red envelopes so the probability of a red is 2/5

Now we multiply all of these so 3/7x1/6x2/5 = .02857142857

To find the percentage, you multiply by 100 so 2.857142857

Im pretty sure they want you to estimate it so 2.86% is what I would put but it depends on your teacher

47 - 90 = 43

43 - 180 = x

x = 137

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
