Julia enjoys shooting paper balls into the wastebasket across her office. she misses the first shot 50% of the time. when she misses on the first shot, she misses the second shot 20% of the time. what is the probability of missing two shots in a row

First, convert the percentages into fractions. Since Julia misses 50% of her first shots, she misses 1/2 of her first shots. Since she misses 20% of her second shots (after missing the first one), she misses 1/5 of her second shots. 

To find the probability of missing two shots in a row, multiply the two fractions together:

1/2 x 1/5 = 1/10

1/10 correlates to 10%. So, Julia has a 10% probability of missing two shots in a row.

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
