Over [174]

Answer:

The expected number of wins for the​ player is 2.31

Step-by-step explanation:

No. of face cards = 12

total cards = 52

Probability of getting face card = \frac{\text{No. of face cards}}{\text{Total No. of cards}}

Probability of getting face card = \frac{12}{52}

The player plays 10​ times

Formula : E=np

n = no. of trials = 10

p = probability of success= \frac{12}{52}

E=expected number of wins

E=10(\frac{12}{52})

E=2.307

So,  the expected number of wins for the​ player is 2.31
