Answer:

The required probability is 0.048

Step-by-step explanation:

Consider the provided information.

Out of 52 card we need to select only 2.

Therefore the sample space is: ^{52}C_2=1326

One card is Ace. The number of Ace are 4 and we need to select one of them.

This can be written as: ^4C_1=4

The second card can be Ten or a Jack or a Queen or a King.

There are 4 Ten, 4 jack, 4 Queen, and 4 king in a deck and we need to select only 1 out of them.

So we can say that we need to select 1 card out of 16.

This can be written as: ^{16}C_1=16

Thus, the probability that one of the cards is an ace and the other one is either a ten, a jack, a queen or a king is:

P=\frac{16\times4}{1326}\approx0.048

Hence, the required probability is 0.048

Inga [223]

Answer:

Amount of green color used =

\dfrac{64}{7}\text{ gallons}

Step-by-step explanation:

We are given the following in the question:

Every  4 gallons of green paint is mixed with 3 gallons of blue paint. to make a particular shade.

Ratio of green color to blue paint can be calculated as:

=\dfrac{\text{Amount of green color}}{\text{Amount of blue color}}\\\\=\dfrac{4}{3}

Amount of shade = 16

Amount of green paint = 4x

Amount of blue paint = 3x

Thus, we can write:

4x + 3x = 16\\7x = 16\\\\x = \dfrac{16}{7}

Amount of green color used =

4x = 4\times  \dfrac{16}{7} = \dfrac{64}{7}\text{ gallons}

Amount of blue paint used =

3x = 3\times  \dfrac{16}{7} = \dfrac{48}{7}\text{ gallons}
