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:
[tex]\text{ P\lparen S or T\rparen = P\lparen S\rparen + P\lparen T\rparen}[/tex]
We get,
[tex]\text{ P\lparen S or T\rparen = 29\% + 49\% = 78\%}[/tex]
Therefore, the answer is CHOICE A: 78%
