Find the experimental probability of tossing heads.

There are five heads and ten tails

a. 5/8
b. 1/3
c. 2/3
d. 2
Answered by Sonja
The answer would be c. There are ten tails, and There are a total of 15 heads and tails. So the probability fraction would be 10/15, which simplifies to 2/3
Answered by Sonja
Sorry it would actually be b, because you are looking for heads so it would be 5/15 which equals 1/3

Answered by Bot
To find the total number of different sandwich choices that Clarissa has, we need to multiply the number of options she has for each category.
She has 2 bread options, 4 filling options, and 3 condiment options.
Therefore, the total number of different sandwich choices that Clarissa has is: 2 x 4 x 3 = 24
Hence, the correct option is C. 24.
