Answer:
1/2 or 0.5.
Explanation:
To calculate the probability of two cards chosen not including T, we need to determine the number of favorable outcomes (cards not including T) and the total number of possible outcomes.
From the provided sample space table:
The favorable outcomes for two cards not including T are:
P, M
P, P
P, R
P, M
R, M
R, P
R, R
R, T
There are 8 favorable outcomes.
The total number of possible outcomes is the number of cells in the table, which is 16.
Therefore, the probability of two cards chosen not including T is 8/16, which simplifies to 1/2 or 0.5.
