The probability of winning on an arcade game is 0.568. If you play the arcade game 22 times, what is the probability of winning
Serggg [28]

The probability of winning 15 out of the 22 games is P = 0.099

<h3>what is the probability of winning more than 15 times?</h3>

We know that the probability of winning on the arcade game is 0.568.

Then the probability of losing is:

P = 1 - 0.568 = 0.432

The probability of winning 15 out of 22 games is given by the equation:

P = C(22, 15)*(0.568)^{15}*(0.432)^{7}

Where C(22, 15) is the number of combinations of 15 elements that we can make with a set of 22 elements, given by:

C(22, 15) = \frac{22!}{(22 - 15)!*15!}  = \frac{22!}{7!*15!} = \frac{22*21*20*19*18*17*16}{7*6*5*4*3*2*1} = 170,544

Then the probability is:

P = 170,544*(0.568)^{15}*(0.432)^7 = 0.099

Order them least to greatest. And explain
AnnyKZ [126]

Answer:

13. 1/2, 5/8, 3/4

16. 7/12, 3/5, 2/3

Step-by-step explanation:

make them have the same denominator.

13) 1/2 x 4 = <u>4/8</u>, <u>5/8</u>, 3/4 x 2= <u>6/8</u>

16) Grab two fractions let's say 3/5 and 2/3

Multiply 3/5 denominator (5) with 2/3 numerator (2)

It's 10 and place it above the number you multiplied the numerator from so it's above 2/3.  Do it again but with 2/3 denominator (3) and 3/5 numerator (3). Multiply 3 and 3 you get 9. Place the 9 above 3/5. We know that 9 is less than 10 so 3/5 is less than 2/3. You can do this with any two fractions.
