Daniel has a jar containing 7 blue marbles,9 white marbles,and 8 red marbles . if daniel remove one marble without looking , records the color,keeps the marble,then removes another marble, what is the probability that he will remove two white marbles?

The probability that Daniel will pick up two white marbles his second time is 37.5% (assuming that Daniel does not pull a white marble out the first time). If Daniel does pick a white marble the first time then the probability that he will pick up two white marbles the second time is 32.5%. 

9+7+8=24. The odds of getting a white marble is the greatest chance. I can't really figure out the percentage or decimal or whatever, but the least I can tell you is that it has a 9/24 or 3/8 chance.

Step-by-step explanation:

sinB = = =

tanC = = =

Thus

sinB tanC = × ( cancel b on numerator/ denominator )

                 =
