Find the probability of the indicated event if $P\left(A\right)=0.25andP\left(B\right)=0.45$

$P(A\cup B)ifP(A\cap B)=0.15$

The probability is $0.55$

The given data is $P\left(A\right)=0.25,P\left(B\right)=0.45,P(A\cap B)=0.15$

Substitute the given values in the formula to find the required value,

$P(A\cup B)=P\left(A\right)+P\left(B\right)-P(A\cap B)\phantom{\rule{0ex}{0ex}}=0.25+0.45-0.15\phantom{\rule{0ex}{0ex}}=0.55$
