Given:

Jennifer writes the letters M-O-N-T-A-N-A on cards.

To find:

The probability of picking an N.

Solution:

We have,

Total number of cards = 7

Total number of cards with letter N = 2

Now, the probability of picking an N is:

$\text{Probability}=\dfrac{\text{Number of cards with letter N}}{\text{Total number of cards}}$

$\text{Probability}=\dfrac{2}{7}$

Therefore, the probability of picking an N is $\dfrac{2}{7}$ .
