P(2 aces) = (1/13)^2
P(2 kings) = (1/13)^2
P(king and ace) = 8C2/52C2 - 2(1/13)^2 = 0.0152
Step-by-step explanation:
Percent of requests for Joseph were:
Total number of requests:
320+750+620+930+800+180=
1070+1550+980=
2620+980=3600.
Which means the percentage is:
1 yard=3ft
1ft=12 in
1yard=36 in
so to solve this problem, you convert everything to the same unit and compare
for this problem I will convert to feet
1yard=3ft
12in=1ft
9.5 yards to feet 9.5 times 3=28.5ft
32.5ft
380in to feet 380/12=31.66666...
so put 28.5, 32.5, and 31.666.... in order from least to greatest
28.5, 31.6666, 32.5
so the answer is 9.5 yd, 380 in, 32.5 ft.
A U B is the set of elements which are in A, in B, or in both A.
Since,
A = {2, 3, 6}
B = {2, 4, 5, 7}
To find A U B, we have to write all numbers that are in A and/or in B. The number that are in both sets must not be written again.
A U B = {2, 3, 6, 4, 5, 7}
Writing then in acending order:
A U B = {2, 3, 4, 5, 6, 7}
Answer: A U B = {2, 3, 4, 5, 6, 7}.
