Find the probability.
Answers
the correct answer is 0.97
Answer:
A) Select and write the most appropriate alternative from the provided in the brackets.
If P(E) = 0.03, then the probability of 'not E' is ____.
[ 0.03, 0.07, 0.97, 1 ]
Answer A) :
We know that, P(E) + P(not E) = 1.
P(E) = 0.03
Hence, 0.03 + P(not E) = 1.
➸ P(not E) = 1 - 0.03
➸ P(not E) = 1.00 - 0.03
➸ P(not E) = 0.97 : Option C.
B) Two dice, one red and other blue are thrown simultaneously. Find the probability of :
a) getting the sum of numbers on their faces greater than 5.
b) getting the score on the second die greater than the score on the first die.
Answer A) :
a) Total number of probability = 36.
The number of favourable outcomes = 36 - 10 = 26.
Hence, P = 26/36 = 0.72.
b) Total number of probability = 36.
The number of favourable outcomes = 15.
Hence, P = 15/36 = 0.41.
