You roll 4 fair, distinguishable, six-sided dice. What is the probability of rolling :______
Vikentia [17]

Answer:

a)0.25

b)0.375

Step-by-step explanation:

Possible outcomes when dice are rolled : 1 ,2 ,3,4,5 ,6

Even= 2,4,6  

Odd = 1 ,3 , 5

Probability of getting even =\frac{3}{6}=\frac{1}{2}

Probability of getting odd = \frac{3}{6}=\frac{1}{2}

4 dices are rolled together

a)P(3 even and 1 odd numbers)

P(3 even and 1 odd numbers)=^4C_3 (\frac{1}{2})^3 (\frac{1}{2})^1

P(3 even and 1 odd numbers)=\frac{4!}{3!1!} (\frac{1}{2})^3 (\frac{1}{2})^1 =0.25

b)P(2 even and 2 odd numbers)

P(2 even and 2 odd numbers)=^4C_2 (\frac{1}{2})^2 (\frac{1}{2})^2

P(3 even and 1 odd numbers)=\frac{4!}{2!2!} (\frac{1}{2})^2 (\frac{1}{2})^2=0.375

jok3333 [9.3K]

Answer:

#1. 8.27

#2. 36

#3. 22

#4. 7.25

Step-by-step explanation:

#1: 60÷11=5.45  ----> 5.45×16=<u>87.27</u> <This is a non-terminating decimal>

#2: 60÷5= 12 ----> 12×3= <u>36</u>

<u></u>

#3: Games- 35    Won- 14    Lost- 21

      In 1 Game  Manchester won =   14/35  =  2/5 games in 54 Game  Manchester won =  54 x  2/5   games

= 108 / 5

= 21.6

<u>= 22</u>

<u></u>

#4: 6 : 91 ⇒ n : 110

     6(110) ⇒ 91(n)

     660 ⇒ 91n

     660/91 ⇒ n

     <u>7.25=n</u>

<u></u>
