This is has two real solutions.
Answer:
Frank is incorrect
Step-by-step explanation:
Frank is incorrect because since the denominator of the ratio is 5 that means in order to get the total amount of marbles inside of the bag the total amount has to be a multiple of 5. And in the three numbers that are given to us there is only one multiple of 5 which is 20 . so, that is why Frank is incorrect.
All of these answers are right
Answer: Hello there!
in a deck of 52 cards, you have 26 red cards and 4 kings, where 2 kings are also red cards, so we could discard them.
We want to know the probability of drawing a red card or a king whem we draw at random, then all the cards have the same probability. This is the quotient between the number of red cards or kings and the total number of cards:
p = 26/52 + 2/52 = 28/52 = 0.48
then you have a 0.48 (or 48%) probability to get a red card or a king.
