A standard deck of cards has 52 cards, 4 of each type (Ace, King, Queen, Jack, 10,...,2). From a well-shuffled deck, you are dea

Wewaii [24]

Answer:

a)%85,5

b)%92,2

Step-by-step explanation:

a) To determine the probability of getting a hand with at least one face, we need to calculate the probability of the hand without any face firstly.

$(36/52)*(35/51)*(34/50)*(33/49)*(32/48)=0,145$

Then, we need to deduct this value from the probability 1

$1-0,145=0,855$

The probability of the hand with at least one face is %85,5.

b)To determine the probability of a hand with at least one ace and face we will track the same road again.

$(32/52)*(31/51)*(30/50)*(29/49)*(28/48)=0,0775$

Then, we need to deduct this value from the probability 1

$1-0,0775=0,922$

The probability of the hand with at least one ace and one face is %92,2.

An ice cream vendor sells three flavors: chocolate, strawberry, and vanilla. Forty five percent of the sales are chocolate, whil

olganol [36]

Answer:

Step-by-step explanation:

Sales of the chocolate ice cream is 45%, 30% for strawberry and 25% (100%-45%-30%) of vanilla.

Percentages of cone sales for chocolate, strawberry and vanilla are 75%, 60% and 40%respectively.

A. Probability chocolate chosen: 45%=0.45

B. Probability strawberry chosen: 30%=0.30

C. Probability vanilla chosen:25%=0.25

D. Probability ice cream on a cone: 75%×45%+60%×30%+40%×25%

=0.75×0.45+0.60×0.30+0.40×0.25

=0.3375+0.18+0.1

=0.6175

E. Probability ice cream in a cup: 1- Probability ice cream in a cone

=1-0.6175

=0.3825

Probability that the ice cream sold on a cone and was strawberry flavoured is : 30%×60%

=0.30×0.60

=0.18

Which two solid figures have the same volume? A. An oblique solid with a base of 4 cm2 and a height of 8 cm B. A cone with a bas

kkurt [141]

In general, Volume is equal to the area of the base multiplied by the height.

Let's check the volume of each.

A.

V=area of base x height, all given, so,

$V=4*8=32$

B.

Volume of cone is given by,

V= one-third area of base x height, all given, so,

$V=\frac{1}{3}*4*8= \frac{32}{3}$

C.

Here, the slant height is given, not the altitude (height). The volume is not 32 nor $\frac{32}{3}$ .

D.

Rectangular solid's volume is area of base times height, all given, so,

$V=4*8=32$

Hence, A and D have same volume.

ANSWER: Option A and Option D have the same volume (32)
