A and B play a game in which they alternately toss a pair of dice. The one who is first to get a total of 7 wins the game. Find

kompoz [17]

Answer: the probability that the first toss wins is:

P = 1/6 or 0.1667

Step-by-step explanation:

A die has six sides (that is 6 outcome per die)

For a pair of dice:

The Total number of possible outcomes = 6 × 6 = 36

The possible outcomes of 7 is:

(1,6),(2,5),(3,4),(4,3),(5,2),(6,1)

= 6

The probability P of getting 7 is:

P = number of possible outcomes of 7/total number of possible outcomes

P = 6/36 = 1/6

The probability that the first toss wins

P = 1/6 or 0.1667

A sales agent makes 40 calls a day. About 15% he calls result in a sale. How many days

Tems11 [23]

Answer: 20 days

Step-by-step explanation:

Since the sale agent makes 40 calls a day and about 15% he calls result in a sale. This means the number of sales will be:

= 15% × 40

= 0.15 × 40

= 6

6 sales out of every 40 calls per day.

The number of calls to make 120 sales will be:

= 15% of x = 120

0.15 × x = 120

0.15x = 120

x = 120/0.15

x = 800 calls

Since he needs 800 calls and he makes 40 calls per day, the number of days needed will be:

= 800/40

= 20 days
