Answer 2

Answer:

The probability that exactly 2 of the cards are spades is 0.315  

Step-by-step explanation:

Given that 6 cards are drawn at random from a standard deck of 52 cards,

we have to find the probability that exactly 2 of the cards are spades.

Total cards=52

Number of cards which are spades=13

Remaining cards=52-13=39

$Probability=\frac{\text{favourable outcomes}}{\text{Total number of outcomes}}$

$Probability=\frac{_2^{13}\txterm{C}\times _4^{39}\txterm{C}}{_6^{52}\txterm{C}}$

$Probability=\frac{\frac{13!}{2!11!}\times \frac{39!}{35!4!}}{\frac{52!}{6!46!}}=0.31512988174\sim 0.315$

Option 3 is correct.
