Answer:

1/2

Explanation:

You want the experimental probability that the next cookie sold will be heart-shaped when Nate's sales so far are the shapes ...

  • diamond: 5
  • heart: 45
  • tree: 2
  • cat: 38

Experimental probability

An experimental probability is a statement of the ratio of the outcome of interest to all of the outcomes experienced.

Nate has sold 5+45+2+38 = 90 cookies. Of these, 45 are heart-shaped, so the fraction of all cookies that are heart-shaped is 45/90 = 1/2.

Nate can expect that the next cookie sold will be heart-shaped with probability 1/2.
