Abasket contains 13 pieces of fruit: 5 apples, 5 oranges, and 3 bananas. jonas takes a piece of fruit at random from the basket, and then beth takes a piece at random. what is the probability that jonas will get an orange and beth will get an apple?

Jonas: 1 of 5 oranges out of 13 pieces of fruit.
p(Jonas picks an orange) = 5/13

Beth: 1 of 5 apples out of 12 pieces of fruit
p(Beth picks an apple) = 5/12

p(Jonas picks an orange and Beth picks an apple) =

= p(Jonas picks an orange) * p(Beth picks an apple)

= 5/13 * 5/12

= 25/156

The probability that Jonas will get an orange and Beth will get an apple
is 25/156

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
