Step-by-step explanation:
Step-by-step explanation:
"The probability of drawing a red ace followed by another ace of any color without replacement."
There are 4 aces total, 2 of which are red. After the first red ace is drawn, there will be 3 aces left. So the probability is:
P = (2/52) (3/51)
P = 1/442
"The probability of drawing a king followed by a queen with replacement."
There are 4 kings and 4 queens. So the probability is:
P = (4/52) (4/52)
P = 1/169
"The probability of drawing a 3 or a 5 followed by a 4 or a 6 with replacement."
There are 8 cards that are either 3 or 5, and 8 cards that are either 4 or 6. So the probability is:
P = (8/52) (8/52)
P = 4/169
"The probability of drawing a spade followed by a jack of any color with replacement."
There are 13 spades, and 4 jacks. So the probability is:
P = (13/52) (4/52)
P = 1/52
Answer:
3.5 and 3½
Step-by-step explanation:
Half of 7 is positive 3.5 aka 3½. It can't be -7/2 or -3.5 because they result in a negative number. It also can't be 7.2 because that's too big of a number.
Answer:
11
Step-by-step explanation:
A square root is any number that is multiplies by itself to get a number.
11*11=121
