Answer:
No. Choosing two dimes are dependent events. The probability of choosing the first dime is 1/4 and the probability of choosing the second dime is 1/7 . The probability that both coins are dimes is
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
The events are dependent.
The size of the original sample space is 8. It changes to 7 after the first dime is chosen.
The probability of picking the first dime is 2/8.
The probability of picking the second dime is 1/7
To find the probability of the compound event, multiply the probabilities.

1/3; 33% chance
Step-by-step explanation:
1/2 (prob. of tossing tails) * 2/3 (prob of rolling < 2) = 1/3
Answer:
Step-by-step explanation:
Probability = 4/46 = 2/23
(2/23) *100 = 200/23 = 8.69% = 8.7%
60,000 times .45= 27000
