Answer:
Step-by-step explanation:
Recall that a <em>probability mass function</em> defined on a discrete random variable X is just a function that gives the probability that the random variable equals a certain value k
In this case we have the event
“The computer will ask for a roll to the left when a roll to the right is appropriate” with a probability of 0.003.
Then we have 2 possible events, either the computer is right or not.
Since we have 4 computers in parallel, the situation could be modeled with a binomial distribution and the probability mass function
This gives the probability that k computers are wrong at the same time.
The probability of picking blue is the number of blue marbles/ total marbles.
For the first pick there are 2 blue marbles and 9 total marbles so the probability of picking blue would be 2/9
After picking the first marble there would be 1 blue marble left and 8 total marbles. The probability of picking the blue marble would be 1/8
To find the probability of picking both, multiply the probability of each one by each other:
2/9 x 1/8 = 2/72, which reduces to 1/36
The answer is 1/36
Answer:
197,250
Step-by-step explanation:
2.5 * 0.04 * 250 * 8 * 1.25 * 789
0.1 * 250 * 8 * 1.25 * 789
25 * 8 * 1.25 * 789
200 * 1.25 * 789
250 * 789
789/4 * 1000
197.25 * 1000
197,250
Answer:
3/10
Step-by-step explanation:
so 1/5 probability
3 is the frequency so
10 times spun
3/10 is the answer
