Answer: 3 : 1

Step-by-step explanation:

We know that the ratio of A to B is given by :-

\dfrac{A}{B} or A : B .

Given : Number of students having brown hair = 15

Number of students having black hair = 5

Then , the ratio of students with brown hair to students with black hair will be  :-

=\dfrac{\text{No. of students with brown hair}}{\text{No. of students with black hair}}\\\\=\dfrac{15}{5}=\dfrac{3}{1}

Hence, the ratio of students with brown hair to students with black hair = 3 : 1.

Answer: 1050

Step-by-step explanation:

Number of combinations of selecting r things out of n = ^nC_r=\dfrac{n!}{r!(n-r)!}

such that ^nC_1=n

Given: A restaurant menu has 5 kinds of soups, 7kinds of main courses, 6 kinds of desserts, and 5 kinds of drinks.

If a customer randomly selects one item from each of these four categories, then by fundamental counting principle , the number of different outcomes are possible = ^5C_1\times \ ^7C_1\times\ ^6C_1\times\ ^5C_1 =5\times7\times6\times5=1050

hence, total number of outcomes = 1050
