4. The number cube shown is rolled and the spinner shown is spun. Find P(an odd number and yellow). The number cube goes up to five. The spinner has four spaces. two are yellow, one is blue and 1 is green.
It must be numbered 0 to 5. Never heard of that before.
odd = 1 3 5
even = 0 2 4
prob of odd = 1/2
colors = 2 y + 1 b + 1 g
so prob y = 2/4 = 1/2
the two events are independent so
p = (1/2)(1/2) = 1/4
it doesnt say, this is what it EXACTLY sais: 4. The number cube shown is rolled and the spinner shown is spun. Find P(an odd number and yellow).
then it has a picture of a cube, 1 on the top, five on the front and 3 on the side. (but i had another question like this, and it used the same cube) but i think the cube doesnt matter... does it? im very confused by this question
with the picture of a spinner, the spinner has landed on the green.
1 green, 1 blue, 2 yellow. 4 tiles in total.
so it wants you to find the probability of an odd number and yellow...???
i don't get it
Well, let's break it down, shall we? There are two possible outcomes that we're interested in: rolling an odd number on the cube and spinning yellow on the spinner.
The cube has 5 numbers, but only 3 of them are odd (1, 3, and 5). So the probability of rolling an odd number is 3/5.
The spinner has 4 spaces, with 2 of them being yellow. So the probability of spinning yellow is 2/4, which simplifies to 1/2.
To find the probability of both events happening, we multiply the individual probabilities: (3/5) * (1/2) = 3/10.
Therefore, the answer is 3/10, which is not one of the options you provided. But hey, life is full of surprises, just like your math problems!
To find the probability of rolling an odd number and landing on yellow, we need to determine the total number of possible outcomes for the number cube and the spinner, as well as the number of favorable outcomes.
The number cube has six faces numbered from 1 to 6. However, in this case, it only goes up to 5. Therefore, there are 5 possible outcomes.
The spinner has four spaces, with two yellow, one blue, and one green. Therefore, there are 4 possible outcomes.
To find the probability of both events occurring (an odd number and yellow), we need to find the number of outcomes where both conditions are satisfied. In this case, there is only one outcome that satisfies both conditions: rolling a 3 and landing on yellow.
Therefore, the probability P(an odd number and yellow) is:
1 favorable outcome / 20 total outcomes = 1/20.
So, the correct answer is 1/20.
