gregori [183]

The probability that he got at least 2 questions correct is 0.756.

Probability is simply how probably something is to appear. every time we're uncertain approximately the final results of an occasion, we can communicate approximately the possibilities of positive outcomes and how in all likelihood they may be. The analysis of occasions ruled through chance is called data.

Basic Probability Rules

  • For any event A, 0 ≤ P(A) ≤ 1
  • The sum of the probabilities of all possible outcomes is 1
  • The Complement Rule
  • Probabilities Involving Multiple Events.
  • Addition Rule for Disjoint Events

Two triangular pyramids are similar the volume of the large pyramids is 729cm and the volume of the smaller pyramids is 64 cm .
lilavasa [31]

Answer:

18 cm for larger base

Step-by-step explanation:

For similar figures, there is a formula regarding volume, area, and length

Large: small =  y: x   for length

large: small = (y^3) / (x^3)  for volume

729 cm cube/ 64 cm cube  = large : small

9: 4  = large: small  by length

large/ 8cm = 9/ 4

large = 8*(9/4) = 2*9 = 18 cm
