Abag contains 13 blue marbles and two white marbles of equal size a marble is randomly selected from the bag set aside and then a second marble is picked what is the probability that two white marbles are picked

Answer as a fraction is 1/105

Answer in decimal form is roughly 0.0095238

Explanation:

There are 13 blue marbles and 2 white. So there are 13+2 = 15 total.

The probability of picking a white marble is 2/15 as there are 2 white out of 15 total. Each marble is equally likely due to the equal sizes.

We do not put the marble back or replace it. This is from the phrasing "set aside", i.e. "no replacement". So there are 2-1 = 1 white left out of 15-1 = 14 total. The probability of picking a white marble again is 1/14

Multiply the two fractions:

(2/15)*(1/14) = (2*1)/(15*14) = 2/210 = 1/105 = 0.0095238

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
