An experiment consists of dealing 7 cards from a standard deck of 52 playing cards. What is the probability of being dealt exact

In-s [12.5K]

Answer: 0.00153

Step-by-step explanation:

Given: An experiment consists of dealing 7 cards from a standard deck of 52 playing cards.

Number of ways of dealing 7 cards from 52 cards = $^{52}C_7$

Since there are 13 clubs and 13 spades.

Number of ways of getting exactly 4 clubs and 3 spades= $^{13}C_4\times\ ^{13}C_3$

Now, the probability of being dealt exactly 4 clubs and 3 spades

$=\dfrac{^{13}C_4\times\ ^{13}C_3}{^{52}C_7}\\\\\\=\dfrac{{\dfrac{13!}{4!(9!)}\times\dfrac{13!}{3!10!}}}{\dfrac{52!}{7!45!}}\\\\=\dfrac{715\times286}{133784560}\\\\=0.00152850224271\approx0.00153$

Hence, the probability of being dealt exactly 4 clubs and 3 spades = 0.00153

There are three consecutive integers such that the sum of the two smallest integers is 17 less than three times the largest.What

abruzzese [7]

ANSWER:

Let the smallest integer = x

x + x + 1 = 3 ( x + 2 ) - 17

2x + 1 = 3x + 6 - 17

2x - 3x = 6 - 17 - 1

- x = - 12

x = 12

FINAL ANSWER:

Therefore, the smallest integer is 12.
