Find the indicated probability.

Ksju [112]

Answer:

$P(B) = 0.55$

Step-by-step explanation:

Given

$P(A\ or\ B) = 0.8$

$P(A) = 0.4$

$P(A\ and\ B) = 0.15$

Required

Find P(B)

In probability, we have:

$P(A\ or\ B) = P(A) + P(B) - P(A\ sd B)$

Substitute values

$0.8 = 0.4 + P(B) - 0.15$

Collect Like Terms

$P(B) = 0.8 - 0.4 + 0.15$

$P(B) = 0.55$

Help plz show work please

Alright, so here we have a cone and a cylinder. The cone has a height of 12. The cylinder has a height of 10.5. Both shapes, because they're on top of each other, have a diameter of 26 or a <em>radius</em> of 13.

Equation for a cylinder: $V_{cylinder} = \pi r^{2} h$

Equation for a cone: $V_{cone} = \frac{1}{3} \pi r^{2} h$

We're going to add both of the volumes of these shapes as soon as we find them.

Cylinder:

$V_{cylinder} = \pi r^{2} h\\= \pi (13)^{2} (10.5)\\\approx 5574.756$

Cone:

$V_{cone} = \frac{1}{3} \pi r^{2} h\\= \frac{1}{3} \pi (13)^{2} (12)\\\approx 2123.717$

Add both values: 2123.717 + 5574.756 = 7698.473 cm³.

Hope this was helpful, let me know if I missed anything!
