Answer:
80%
Explanation:
To calculate the probability of NOT choosing the card with the number 2 from the pile, we need to find the probability of choosing any card other than the card numbered 2.
There are a total of 5 cards in the pile, numbered from 1 through 5. Since we want to find the probability of not choosing the card with the number 2, we need to determine the number of favorable outcomes (not choosing 2) and the total number of possible outcomes (choosing any card from the pile).
Number of favorable outcomes (not choosing 2): There are 4 cards other than 2 (1, 3, 4, and 5).
Total number of possible outcomes (choosing any card from the pile): There are 5 cards in total.
Now, we can calculate the probability:
Probability of NOT choosing the card with the number 2 = Number of favorable outcomes / Total number of possible outcomes
Probability of NOT choosing the card with the number 2 = 4 / 5
Therefore, the probability of NOT choosing the card with the number 2 is 4/5 or 0.8 (80%).
