LCM is found by finding the factors of both and making sure that both are inthere
9=3 times 3
12=2 times 2 times 3
common one is 3
so we have to have at least 2 threes and 2 twos
2 times 2 times 3 tiimes 3=36
answer is 36
Answer:
190
Step-by-step explanation:
100x10x9/100=90
balance=100+90=190
Answer:
0.7
Step-by-step explanation:
Probability of defective = 0.7
P(non-defective) = 1 - 0.7 = 0.3
Let X be the trial at which we get the first non-defective
Then X follows a geometric distribution.
X ~ Geo (0.3)
What has happened already will not affect the probability.
P(atleast 2 more) = P(X > 1)
= 1 - P(X = 1)
= 1 - (0.3)
= 0.7
It should be 7 tens because both side should be equal.
