Answer:
<u>P = 20</u>
Step-by-step explanation:
<u>Mean</u>
- 18.75 = 10(5) + 15(10) + P(7) + 25(8) + 30(2) / 32
- 18.75 × 32 = 50 + 150 + 7P + 200 + 60
- 600 = 460 + 7P
- 7P = 140
- <u>P = 20</u>
12/X=X/6
X^2=72
X= 8.48
X=8.5
18/y=y/12
Y-^2= 216
Y= 14.69
Y= 14.7

Answer: 0.00000565
Step-by-step explanation:
Required to win:
6 number match $10,000
5 number match $ 5,000
4 number match $ 1000
3 number match $ 5,00
2 number match $ 50
1 number match $ 10
Therefore, to win $10,000 ;
All 6 numbers must match
Number of right numbers = 6
Total numbers = 25
Since it is without replacement :
Probability = required outcomes / Total possible outcomes
P(First number match) = 6/25
P(second number match) = 5/24
P(third number match) = 4/23
P(fourth number match) = 3/22
P(fifth number match) = 2/21
P(sixth number match) = 1 / 20
Therefore, Probability of winning $10000 :
(6/25) * (5/24) * (4/23) * (3/22) * (2/21) * (1/20) = 720 / 127512000 = 0.0000056465
= 0.00000565
