help math please

Leander rolls a standard die twice. Which of the following compound events has the greatest chance of occurring? the probability of 2 and 2 the probability of 2 and 5 the probability of 5 and even the probability of even and even

OpenStudy (thecatman):

this stuff is hard

OpenStudy (anonymous):

ask @amistre64 for that..

OpenStudy (thecatman):

@amistre64

OpenStudy (thecatman):

i dont think he is on

OpenStudy (amistre64):

when in doubt, draw up a table ....

OpenStudy (amistre64):

1 2 3 4 5 6 1 (1,1) (1,2) (1,3) 2 3 4 5 6 and so on

OpenStudy (thecatman):

this is very hard for me

OpenStudy (amistre64):

logically, there are more "even" numbers than "single" numbers so the chance that an even number happens is very high; 1/2

OpenStudy (amistre64):

the chance that a single value presents itself is just 1/6

OpenStudy (amistre64):

since the first 2 probabilities are the same: #,# we cant choose both of them as correct can we? #,even would be calculated as: 1/6 * 1/2, and there are a few ways that could happen even,even would be calculated as: 1/2 * 1/2, and there are a few ways that could happen

OpenStudy (amistre64):

without any calculations, which one do you think has the best chance of happening?

OpenStudy (thecatman):

2 and a 2

OpenStudy (amistre64):

2,2, or 2,2; 2 out of 36 2,5 or 5,2; 2 out of 36 5,2 or 5,4 or 5,6 2,5 or 4,5 or 6,5; 6 out of 36 2,2 or 2,4 or 2,6 4,2 or 4,4 or 4,6 6,2 or 6,4 or 6,6; 9 out of 36

OpenStudy (amistre64):

the more ways there are to get a favorable outcome, the higher the probability of it happening

OpenStudy (amistre64):

since 9 is the biggest pool of events .... id say the even,even has the highest chance of occuring

OpenStudy (thecatman):

Horatio has a pack of candies containing 4 strawberry, 2 lemon, 1 lime, and 3 orange flavored chews, in random order. If he eats each candy immediately after taking it out of the pack, which multiplication expression can be used to determine the probability that the first two candies he eats are lemon? two-ninths times one-ninth two-tenths times one-ninth two-tenths times one-tenth two-tenths times two-tenths can you help me with this one

OpenStudy (amistre64):

we would perfer that if a question is satisfied, that you close it and post a new one. This allows others the chance to gain medals for best responses.
