A magician showed a magic trick where he picked one card from a standard deck. Determined what the probability is that the card
8_murik_8 [283]

Answer:

7 / 13

Step-by-step explanation:

The number of cards in a standard deck = 52

Number of red cards in a deck = 26

Number of queens in a deck = 4

Selecting a card at random ;

Probability of picking a red card ;

P(red card) = number of red cards / number of cards in deck

P(red card) = 26 / 52

P(queens card) = number of queens / number of cards in deck

P(queens card) = 4 / 52

Number of red queen cards = (red n queen) = 2

P(red or queens card) = P(red) + P(queens) - P(red n queen)

P(red or queens card) = 26/52 + 4/52 - 2/52

= (26 + 4 - 2) / 52

= 28 /52

= 7 / 13

Fernando loves to make music playlists. He likes to keep the same ratio of country songs to rock songs. On his summer playlist,
Ede4ka [16]

Answer:

There are 6 rock songs on Fernando's road trip playlist.

Step-by-step explanation:

Given that he keeps the ratio same

This means that the ratios for both summer playlist and trip playlist will be the same

Let

c1 be the country songs in summer playlist

r1 be the rock songs in trip playlist

Similarly,

c2,r2 will be the country and rock songs in trip playlist

Both will be equal so

\frac{c_1}{r_1} = \frac{c_2}{r_2}

Putting the values

\frac{100}{24} = \frac{25}{r_2}\\100r_2 = 25*24\\100r_2 = 600r_2 = \frac{600}{100}\\r_2 = 6

Hence,

There are 6 rock songs on Fernando's road trip playlist.
