Answer: 15/16
Step-by-step explanation:
There will be 16 outcomes for 4 coins=2^4
Probability of only head is : P(C)=1/16
P(C) + P(C') = 1
P(C') = 1 - P(C)
P(C') = 1 - 1/16
Take the l.c.m
P(C') = (16-1) / 16
P(C') = 15/16
So the probability of getting at least 1 tail is 15/16
Answer: C.3
Explanation: if 5 times 3 equals 15 plus 2 is 17
It would be x is greater then 3 so anything above 3 which would be 5
So the answer is
(4) 5
Apply the Pyth. Theorem:
c^2 = 3^2 + 7^2, or c^2 = 9 + 49 = 58. Thus, c = sqrt(58).
Answer:
The answer would be 12%
Step-by-step explanation:
250-220=30 and 30 is 12% of 250
