Answer:
P(not blue) = 3/5
Step-by-step explanation:
There are 4 blue shirts, 2 brown shirts , 2 green shirts, 1 red shirt and 1 white shirt for a total of 10 shirts
How many shirts are not blue?
2 brown shirts , 2 green shirts, 1 red shirt and 1 white shirt for a total of 6 shirts
P( not a blue shirt) = not a blue shirt/total
= 6/10
=3/5
This is a statistics problem on permutation and combination. To differentiate this, permutation involves on the arrangement in which order doesn't matter. For combination, order matters.
For example, if you arrange A, B and C, for permutation it could be AB, BA, CA, AC, BC and CB. But for combination, it would just be AB, AC and BC.
So, in this problem where he is asked to arrange 8 jars in which order doesn't matter. It is permutation. You can solve this just by calculator. The formula would be nPr, where n is the total number of items while r is the number of items to be sorted. Thus,
nPr = 10P8 = 1, 814,400
Thus, the answer is B.
20% of $20 is $4
So add that amount to the price of the meal and you have $24
Since they split the total cost evenly, the price for each is 24 ÷ 2
= <u>$12</u>
