tester [92]

Answer:

The probability that neither is available when needed

$P(A n B)^{c} = 0.04$

Step-by-step explanation:

A town has 2 fire engines operating independently

Given data the probability that a specific engine is available when needed is 0.96.

Let A and B are the two events of two fire engines

given P(A and B) = 0.96 ( given two engines are independent events so you have to select A and B)

Independent events : P( A n B) = P(A) P(B)

The probability that neither is available when needed

$P(A n B)^{c} = 1- P(A n B)$

$P(A n B)^{c} = 1- 0.96 = 0.04$

If two cards are drawn without replacement from a deck, find the probability that the second card is a spade, given that the fir

madam [21]

There are 13 spades in a standard deck of cards, so if the first one is a spade, there are 12 spades left.

So the chances of getting another one would be 12/52 because there are 52 cards in a standard deck of cards.

Reduced, your answer is 3/13
