Vadim26 [7]

Answer:

The expected value of the number of spades are = 4.25

Step-by-step explanation:

As per the question,

W know that in a standard deck of 52 playing card, there are 4 suits, and each suit have 13 playing card.

Since, we know that

Probability\ of\ a \ event\ = \frac{Number\ of\ Favorable\ Outcomes}{Total\ Number\ of\ Possible\ Outcomes}

Therefore,

Probability of any random card being a spade is

=\ \frac{13}{52}

=\ \frac{1}{4}

So the expected number of spades we draw are

=\ \frac{1}{4} \times 17

=\ 4.25

Hence, the expected value of the number of spades are = 4.25
