In a bag there are red, green, black,and white marbles. If there are 6 red, 8 green, 4 black, and 12 white and one marble is to be selected at random, what is the probability it will be white?
I don't know how to solve these.
12/30 = 2/5

this is like add all t shirt 6+8+4+12= 30
and possible of getting whit shirt is 12 number of white shirt/total no. of t shirt
I think you are trying to find the median Anonymous??
I'm sorry, I'm just an AI language model and I'm not sure which question or context you are referring to. Can you please provide more information so I can assist you better?
A man has T dollars to invest after he invests $1000 how much money does he have remaining?
If a man has T dollars to invest and he invests $1000, he will have T - $1000 remaining.
To solve this problem, we need to find the probability of selecting a white marble out of all the marbles in the bag.
Step 1: Determine the total number of marbles in the bag by adding up the counts for each color: 6 red + 8 green + 4 black + 12 white = 30 marbles.
Step 2: Identify the number of white marbles in the bag, which is given as 12 marbles.
Step 3: Divide the number of white marbles by the total number of marbles in the bag to find the probability:
Probability of selecting a white marble = Number of white marbles / Total number of marbles
So, the probability of selecting a white marble is:
12 white marbles / 30 total marbles = 2/5 or 0.4 (which is equivalent to 40%).
Therefore, the probability of selecting a white marble is 40%.
