Answer:

0.956

Step-by-step explanation:

X is the random variable representing the number of successes in the experiment in question;

X is represented by a binomial distribution with 5 trials and 0.18 probability of success, X~B (5, 0.18);

The probability of r successes, P(X=r), is found using the formula shown in second pic;

Working is shown in the other pic.

Drag each expression to show whether it can be used to find the volume, surface area, or neither.

Mumz [18]

Answer:

Volume = 12 *6 *8 , Surface area = 2 ( 12 *6 + 8 *12 + 6* 8 )

Step-by-step explanation:

Given : Cuboid with length 12 , width 6 and height 8 units.

To find : Drag each expression to show whether it can be used to find the volume, surface area, or neither.

Solution : We have given Cuboid with

Length = 12 units ,

Width = 6 units

Height = 8 units.

Volume of cuboid = length * width * height .

Volume = 12 *6 *8.

Surface area = 2 ( l *w + h *+w *h)

Surface area = 2 ( 12 *6 + 8 *12 + 6* 8 ).

None = 12 +6 +8.

Therefore, Volume = 12 *6 *8 , Surface area = 2 ( 12 *6 + 8 *12 + 6* 8 ) .
