Brums [2.3K]

Answer:

option B (28/52)

Step-by-step explanation:

from probability

P(A∪B)=P(A)+P(B)-P(A∩B)

where

P(A∪B) = probability that event A or B happen

P(A∩B) = probability that event A and B happen simultaneously

P(A) = probability that event A happen

P(B) = probability that event B happen

the probability that the card is special or red

P( special or red)= P(special) + P(red) - P( special and red)

since

P(special)= 4/52

P(red) = 26/52

P( special and red) = 2/52

therefore

P( special or red)= 4/52 + 26/52 - 2/52 = 28/52

P( special or red)= 28/52

How to add fractions with unlike denominators?

Ainat [17]

Change the fractions so they have common denominators. For example. If adding 4/8 + 2/3, a common denominator of the two could be 24. Change both fractions to have a denominator of 24. To do this:

(4/8)×(3/3)= 12/24
(2/3)×(8/8)=16/24

Now that both fractions have denominators of 24, you can simply add the numerators to get your answer. in this case, it would be 28/24
