Question

An experiment results in one of the sample points upper e 1e1​, upper e 2e2​, upper e 3e3​, upper e 4e4​, or upper e 5e5. complete parts a through
c.
a. find ​p(upper e 3e3​) if ​p(upper e 1e1​)equals=0.10.1​, ​p(upper e 2e2​)equals=0.10.1​, ​p(upper e 4e4​)equals=0.20.2​, and ​p(upper e 5e5​)equals=0.30.3.

Answer 1

Given that an experiment results in one of the sample points E1, E2, E3, E4, or E5.

Then P(e1) + P(e2) + P(e3) + P(e4) + P(e5) = 1

If P(E1)=0.1, P(E2)=0.1, P(e4)=0.2, and P(E5)=0.3., then P(E1) = 1 - 0.1 - 0.1 - 0.2 - 0.3 = 0.3

Therefore, P(e3) = 0.3
