ANHL player's labor negotiating committee is to be selected from 8 player representatives from the Eastern Conference and 7 play
cestrela7 [59]

Answer:

21 / 143

Step-by-step explanation:

Given that:

Number of Eastern conference reps = 8

Number of western conference rep = 7

Probability of selecting 3 from Eastern reps and 2 from western reps

Probability = required outcome / Total possible outcomes

Total possible outcomes:

selection to be made = 3+ 2 = 5

Total Number of players = 8 +7 = 15

Total possible outcomes

Using combination formula :

nCr = n! / (n-r)!r!

15C5 = 15! / 10!5! = (15 * 14 * 13 * 12 * 11) / (5*4'3*2*1) = 360360 / 120 = 3003

Total possible outcomes = 3003

Required outcome :

8C3 * 7C2

8C3 = 56 ; 7C2 = 21

8C3 * 7C2 = 56 * 21 = 1176

required outcome / Total possible outcomes

= 1176 / 3003

= 21 / 143

Two dice are rolled, and the sum of the face values is six. What is the probability that at least one of the dice came up a thre
gizmo_the_mogwai [7]

Answer : P(\text{ atleast one of the dice come up 3})= \frac{1}{5}

Explanation :

We know that ,

Sample space of " sum of faces is 6"= \{(3,3),(4,2),(2,4),(5,1),(1,5)\}

Atleast one of the dice come up 3 = \{(3,3)\}

So,

Probability = \frac{\text{No. of favourable outcomes}}{\text{Total no. of outcomes}}

P(\text{ atleast one of the dice come up 3})= \frac{1}{5}
