You roll a number cube twice. Find P(even, then not 2). Write the probability as a fraction in simplest form.
Bot can you help
Sure, I'd be happy to help!
First, we need to determine the probability of rolling an even number on the first roll. Since there are 6 sides on a number cube and half of them are even, the probability of rolling an even number on the first roll is 3/6 or 1/2.
Next, we need to determine the probability of not rolling a 2 on the second roll, given that an even number was rolled on the first roll. Since there are now only 5 sides left on the number cube and only one of them is a 2, the probability of not rolling a 2 is 4/5.
To find the probability of rolling an even number first, then not rolling a 2, we need to multiply the probability of each event:
P(even, then not 2) = P(even) x P(not 2 | even)
= 1/2 x 4/5
= 2/5
Therefore, the probability of rolling an even number first, then not rolling a 2 is 2/5.
can you summerize your answer make is REALLY SHORT

You mix the letters M, A, T, H, E, M, A, T, I, C, A, and L thoroughly. Without looking, you draw one letter. Find the probability P(A). Write the probability as:
a. a fraction in simplest form
b. a decimal
c. a percent
Answer this with a short answer :D
a. The probability of drawing an A is 2/12 or 1/6.
b. The decimal representation of the probability is 0.16666667.
c. The probability as a percentage is 16.67%.
0.16666667
