the deck. what is the probability that amar will draw a spade in the first five attempts?
o 24%
o45%
076%
o 81%

The required probability is, 0.78

Step-by-step explanation:

There are, (52 - 13) = 39 cards which are not spade

5 cards can be chosen from the deck of 52 cards in

 ways

and out of these 5 choices, none of them will be spade in,

 ways

So,

P(None of the chosen cards is spade)

=

Hence,

P(out of these 5 choices, at least one card is spade)

= 0.78

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
