Abox contains eight cards labeled p, q,r, s,t, u,v, and w. one card will be randomly chosen.
what is the probability, of choosing a letter from p to r?
write your answer as a fraction in simplest form.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
