Which table correctly shows all the sample spaces for tossing a coin and rolling an odd number on a six-sided number cube?
a and b are first picutre c and d are last picture

@welshfella @waterineyes @Mr.Z
well the numbers on cube must be 1 , 3 or 5 and coin has to be heads or tails
@Preetha
an example of an outcome would be heads,5 but heads,2 would not be an outcome because the number must be odd
the sample space is a list of all the possible valid outcomes
do you know the answer
@hotguy
yes - but you should be able to work it out from the information I've given you. Check the 4 tables - its can;t be c or d for example because the numbers on the cubes are even. (2,4 and 6)
i was thinking b
@welshfella
@TheSmartOne
are all the numbers in table b odd?
if any one is even then it cant be table b.
nonono so its a???
correct
could you help me with this one :/
A box has 8 beads of the same size, but all are different colors. Tamy draws a bead randomly from the box, notes its color, and then puts the bead back in the box. She repeats this 3 times. What is the probability that Tamy would pick a red bead on the first draw, then a white bead, and finally a red bead again? 1 over 4096 1 over 512 1 over 64 1 over 8
the probability of picking a particular colour is 1/8 with repeated draws you multiply the probabilities so for 2 draws it would be 1/8 * 1/8
wait so my answer is 1/8
or no
n0 - there are 3 draws so multiply 3 probabilities
as i said for 2 draws its 1/8 times 1/8 so for 3 its ?
