Answer:
Below.
Step-by-step explanation:
2)
(a) Prob(exactly 6 marks) = 2/10 = 1/5
(b) Prob(At least 6 marks) = 5/10 = 1/2.
3)
Prob ( Queen of hearts) = 1/52
4)
Probability of a 6 in one throw = 1/6.
So expected number of 6's in 300 throws
= 1/6 * 300
= 50.
Answer: 3/8
Step-by-step explanation:
Formula is,
P(A|B) = P(A and B) / P(B)
= (3/10) / (4/5)
= 3/8
