Answer:
This states that the probability of the occurrence of two independent events is the product of their individual probabilities. The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.
Step-by-step explanation:
The probability of getting 2 heads with 2 coins can be broken into 2 steps:
The first coin must show Heads AND
the second coin must show Heads.
p(h,h)= P(H) <----- and means multiply
P(H) x P(H)= 1/2 x 1/2 =1/4
Answer:(5,12)
Step-by-step explanation: 2.5 x 2= 5
6 x 2= 12
Answer:
DE = 24
Step-by-step explanation:
The midsegment DE is half the length of the third side AC , that is
DE = 
AC = × 48 = 24
Answer:
495
Step-by-step explanation:
From 12, choose 4:
₁₂C₄ = 12! / (4! (12−4)!)
₁₂C₄ = 12! / (4! 8!)
₁₂C₄ = 495
Answer:
Step-by-step explanation:
3/5 + 1/3
taking lcm we get 15
=<u> 3 * 3 + 1 * 5</u>
15
= <u>9 + 5</u>
15
=14/ 15
