Answer 3

please help

Answer 4

Do u know how to calculate basic probability?

Answer 5

yes

Answer 6

add up all the outcomes
the probability of getting a 1 is 7 divided by this sum ( times 100 for percentage.

calculate the probabilty of a 6 in a similar way.

now, do you add or multiply these probabilities to get the final answer?

Answer 7

yes

Answer 8

lets write prob of rolling 1 as P(1) and prob of rolling 6 as p(6)
then P(1) = 7/30 [ as there 30 outcomes on total and 7 are favourable]
and P(6) = 4/30

now P(1) or P(6) is adding both probabilities we get 11/30

Answer 9

thx

Answer 10

to get percentage , u have to multiply it with 100

Answer 11

i dont know

Answer 12

what is it you dont know ? why you add them?

Answer 13

i tried to add it up it did not work

Answer 14

i dont have probilty caculator
