Answer 1

Answer:   180

Step-by-step explanation:

Given : A bag contains three red marbles, five green ones, one lavender one, two yellows, and six orange marbles.

The number of ways to choose one thing out of n is given by:-

$^nC_1=\dfrac{n!}{1!(n-1)!}=n$

Number of ways to choose one red marble out of 3= $^3C_1=3$

Number of ways to choose one green marble out of 5= $^5C_1=5$

Number of ways to choose one yellow marble out of 2= $^2C_1=2$

Number of ways to choose one orange marble out of 6= $^6C_1=1$

By using the Fundamental counting principle , we have

The number of sets of four marbles include one of each color other than lavender will be :-

$3\times5\times2\times6=180$

Hence, the number of sets of four marbles include one of each color other than lavender =180
