If you roll two number cubes, what is the probability of their sum being seven or higher?

Answers

Answer 1

Answer: 1) Number of possible outcomes when 2 cubes are rolled = n^2 = 6^2 = 36
Possible outcomes for a sum = 7 are 6 as detailed below
(1,6) (2,5) (3,4) (4,3) (5,2) (6,1) = 6
Possible outcomes for a sum = 11 are 2 as detailed below
(5,6) (6,5) = 2
Required probability = 6/36 + 2/36 = 8/36 = 0.22222

2) Number of possible outcomes when a cube and a coin are tossed = m*n = 6*2 = 12
Possible outcomes for a tail and 6 = 1
Required probability = 1/12 = 0.08333

3) Possible outcomes for a sum =3 are 2 as detailed below
(1,2) (2,1) = 2
Possible outcomes for a sum = 8 are 5 as detailed below
(2,6) (3,5) (4,4) (5,3) (6,2) = 5
Required probability = 2/36 + 5/36 = 7/36 = 0.19444

Answer 2

Answer: 27 rolls of being 7 or higher

Joe has eaten of a pizza. Jane has eaten of a pizzaHow many times more pizza has Joe eaten than Jane?

Answers

it's 3/5-1/7
(21-5)/35
16/35

Joe has eaten (21/5) times more than Jane.
Divide (3/5) with (1/7)...you'll get 21/5
If you want to check this, multiply 21/5 by 1/7....you'll get 3/5 which is what Joe has eaten!

An athlete is making an appearance and signing autographs at a new sporting goods store. He agrees to give 20% of his profit to youth sports programs and 5% of his profit to his manager. If he profits $1,000.00 selling autographs and merchandise, how much of that profit does he take home?

Answers

Answer:

He will take $ 750.

Step-by-step explanation:

Given,

His total profit = $ 1000,

Since, The amount he gave to youth sports programs = 20 % of his total profit = 20 % of 1000

= 0.2 × 1000

= $ 200

Also the amount he gave to his manager = 5 % of his total profit,

= 5 % of 1000

= 0.05 × 1000

= $ 50

Thus, the total amount he gave = $ 200 + $ 50 = $ 250

Since, the amount he will take home = Total profit - The amount he gave

= 1000 - 250

= $ 750

100%-20%-5%=75%
75%x$1000=$750
$750 is the answer
