This problem could be solved through using the combination in your scientific calculator. First, the probability must be presented in a fraction, wherein the numerator is the number of possibilities for a given condition and the denominator is the number of all possibilities.
For the numerator, using the counting principle:
2 out of 4 vegetables* 1 out of 2 meats * 1 out of 2 cheese
4C2 * 2C1 * 2C1 = 24
For the denominator,
4 toppings out of 8 available toppings = 8C4 = 70
The 8 toppings consist of 4 vegetables + 2 meat + 2 cheese
Thus, the probability would be 24/70 or 12/35.
You didn’t send an image so i’m just going to guess. I will guess 2/5
For the first question,
Square-root 5 is NOT a rational number.
It’s irrational because, in decimal form, the number goes on forever and has no repeating numbers in decimal form.
Question 2
Pi is NOT rational.
Pi goes on forever and doesn’t repeat.
Add 2 to both sides then divide 9 from both sides :)
