Question

Can u help please? (graph attached)

If the probability of the shaded area is 60%, find P(X≤3)

Answer 1

the whole region has to be \(100\%\)
subtract \(60\%\) to give the unshaded part, then take half of that

Answer 2

ok thx ill try that

Answer 3

ummm ok that doesnt make any sence to me sry
subtract 60% from what?

Answer 4

Answer 5

You can set up an equation as satellite mentioned:
\[\underbrace{A}_{\large P(X\le3)}+\underbrace{60}_{\large P(3\le X\le5)}+\underbrace{A}_{\large P(X\ge5)}=\underbrace{100}_{\large\text{total area}}\]
Solve for \(A\).
