Refer to a standard deck of playing cards. Assume 5 cards are randomly chosen from the deck. How many hands contain 4 aces?
Setler79 [48]

There would be 0.07923 probability to get 4 aces.

<h3>What is probability ?</h3>

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Total number of cards in deck = 52

Total number of aces = 4

When 5 cards are chosen randomly,

The probability to get 4 aces

= 1/52+1/51+1/50+1/49+0

Since, at 5th time there will be no ace remains, so probability would be 0.

= 0.01923+0.01960+0.0200+0.0204

=0.07923

It is known that 60 percent of all registered voters in the 42nd Congressional District are Republicans. Three registered voters
Gelneren [198K]

Answer:

0.11

Step-by-step explanation:

Let x be a random variable representing the number of registered voters in the congressional district. This is a binomial distribution since the outcomes are two ways. It is either a randomly selected registered voter is a conservative or not. The success would be that a randomly selected voter is a conservative. The probability of success, p = 60/100 = 0.6

The probability of failure, q would be 1 - p = 1 - 0.6 = 0.4

Given n = 10, we want to determine P(x = 4)

From the binomial distribution calculator,

P(x = 4) = 0.11
