That looks complicated but Photomath works really well! It help explain things
21x - 14
Explanation:
you distribute the 7, and first multiply it by 3x to get 21x. Then you distribute the 7 and multiply it by the -2 to get -14.
Hope this helps!
Tina has two bags of counters. Bag A has 5 red and 3 blue. Bag B has 4 red and 5 blue. The probability that tina takes two blue counters in fraction is 15/72
<h3>What is the probability?</h3>
Given parameters:
Bag A= 5 red + 3 blue
Bag B = 4 red + 5 blue
Hence,
Total counters in bag A = 5 +3 = 8
Total counters in bag B = 4 + 5 = 9
Now let determine the probability that she takes two blue counters
Probability = 3 /8 × 5 /9
Probability = 15 / 72
Therefore 15 / 72 is the probability that two blue was taken.
