We are given that Donna knit a total of 12 blankets.

She took 4 months in doing it.

To find the number of blankets in 1 month, take ratio of number of blankets to number of months.

$\frac{number \: of \: blnkets}{number \: of \: months} \\ \\ = \frac{12 \: blankets}{4 \: months} \\ \\ = \frac{3 \: blankets}{1 \: months}$

Thus, she knit 3 blankets in 1 months

Readme [11.4K]

Answer:

The number of ways is 26,400 ways

Step-by-step explanation:

Given;

total number of men, M = 10

total number of women, W = 12

number of committees to be formed = 6

If there must be equal gender, then it must consist of 3 men and 3 women.

$The \ number \ of \ ways = 10C_3 \times 12C_3\\\\The \ number \ of \ ways =\frac{10!}{3!7!} \times \frac{12!}{3!9!} \\\\T he \ number \ of \ ways = 120 \times 220 = 26,400 \ ways$
