Abead is chosen randomly from a golf bag. if 40% of the beads are spears and 30% of the spheres are blue what's the probability of choosing a blue sphere?
a. 75%
b. 1.2 %
c. 12%
d. 10%

c. 12%

Step-by-step explanation:

40% of the beads are spears, you can convert it to 0.4

30% of the spheres are blue, you can convert it to 0.3

=> probability choosing blue sphere = (0.4 * 0.3)*100(%) = 12%

My explaination may not really clear but the answer is correct. Hope this help!

In this question, we're trying to figure out the probability of choosing a bead that's a sphere and is blue.

In this case, we know that:

With the information above, we can solve the question.

We don't know the exact amount of beads in the bag, so we would use 10 beads as an example (since 10 beads would equal 100%).

We know that we have a 40% chance of getting a sphere bead, so our probability is currently at 40% or 0.4

30% of those spheres are blue.

So what we would do is find the chances of picking a blue spherer from the total amount of spheres.

To do this, we would multiply 0.4 by 0.3

Your answer would be C). 12%

i would pic false cause it goes down towards negative

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
