Question

Suppose s and t are mutually exclusive events. find p (s or t) if p(s)=29% and p(t)=49%

Answer 1

Given:

P(s) = 29%

P(t) = 49%

For us to be able to determine P(S or T), we will be using the following formula:

`\text{ P\lparen S or T\rparen = P\lparen S\rparen + P\lparen T\rparen}`

We get,

`\text{ P\lparen S or T\rparen = 29\% + 49\% = 78\%}`

Therefore, the answer is CHOICE A: 78%
