What is the probability of selecting a odd number from number 1-25?
from 1-25 there are 25 numbers 1 3 5 7 9 11 13 15 17 19 21 23 25 = 13 numbers [2 4 6 8 10 12 14 16 18 20 22 24 = 12 numbers] so probability of selecting an odd number is 13 in 25 13:25
What is the probability of rolling a sum of 10 or a sum that is an odd number when two number cubes are rolled?
The probability is 21/36 = 7/12
What is the probability that you will pick an odd number or a number greater than 13 from 1 to 20?
It is 14/20 or 7/10.
You ask a friend to think of a number between four and twelve what is the prbability it will be odd?
Assuming he has to pick a whole number his possible choices are 5, 6, 7, 8, 9, 10 and 11. Four of these seven possibilities are odd numbers so the probability of him choosing an odd number is 4/7.
What is the formula if you have 20 people on a basketball team 45 people on a football team 10 are on both--how many ways can a person be selected from either team?
Let P(A) = 1/10; P(A) = probability of selecting one people on a basketball team P(B) = 1/35; P(B) = probability of selecting one people on a football team P(C) = 1/10 = probability of selecting one people who plays in both teams P(D) = probability of selecting from either team. P(D) = P(A) + P(B) - P(C) P(D) = 1/10 + 1/35 - 1/10 P(D) = 1/35 or 0.0286
