Answer 1

Solution

$\small \mathbf{given:}\;P(A)=0.65,\;P(B)=0.69,\;P(A\;and\;B)=0.51$

$\small \mathbf{find:}\;P(A\;or\;B)=?$

formula : P(A or B) = P(A) + P(B) - PA and B

Plug in all the given values

$\small P(A\;or\;B)=0.65+0.69-0.51$

$\small \mathbf{P(A\;or\;B)=\mathbf{{\color{Red} 0.83}}}$
