How many multiples of 3 are there on a single die? How many multiples of 4?
OpenStudy (anonymous):
1. multiple of 3 is 3,6 and multiple of 4 is 4
so numbers are 3,4,6
p(multiple of 3 or 4) = 3/6 =1/2
OpenStudy (anonymous):
2. multiple of 2 are 2,4,6 and multiple of 3 are 3,6
so, common numbers are 2,3,4,6
P(multiple of 2 or 3) =4/6 =2/3
OpenStudy (anonymous):
3*2=6
4*1=4?
OpenStudy (anonymous):
3 is also a multiple of 3

3*1=3?
OpenStudy (anonymous):
there are only two number multiple of 3 that is 3 and 6
OpenStudy (anonymous):
and there is only one multiple of 4 in a dice that is 4 itself
OpenStudy (anonymous):
than we have 3,6,4 ?
OpenStudy (anonymous):
yes , only number multiple for multiple of 3 or 4

are 3,4,6
OpenStudy (anonymous):

OpenStudy (anonymous):
how about 2)?
OpenStudy (anonymous):
2. multiple of 2 are 2,4,6 and multiple of 3 are 3,6
