Answer:

The number of days when Kimmy play for two hours a day is 3.

Step-by-step explanation:

Let the number of days when Kimmy play for two hours a day be x. So, the number of days when Kimmy play for three hours a day is 9-x.

It is given that Kimmy has played video games 24 hours over the last 9 days.

2(x)+3(9-x)=24

2x+27-3x=24

-x+27=24

Subtract 27 from both the sides.

-x=24-27

-x=-3

x=3

Therefore the number of days when Kimmy play for two hours a day is 3.

Georgia [21]

Answer:

65.3%

Step-by-step explanation:

Binomial distribution PMF below (along with a description)

the probabilty of getting 2, 3, or 4 successes in 5 trials is just

p(2)+p(3)+p(4)

p(2)= 5C2*.4²*(1-.4)³ = .3456

p(3)= 5C3*.4³*(1-.4)²= .2304

p(4)= 5C4*.4⁴*(1-.4)=.0768

.3456+.2304+.0768= .6528
