Answer:
1/ 8
Step-by-step explanation:
Given that:
Number of red cards in deck = 26
Number of diamonds in deck = 13
Number of cards in deck = 52
Recall :
Probability = required outcome / Total possible outcomes
Probability of choosing a red :
P(red) = 26 / 52 = 1/2
With replacement :
Probability of diamond :
P(diamond) = 13 / 52 = 1/4
Hence,
Probability of first card red, then second card diamond equals
P(red) * P(diamond)
1/2 * 1/4
= 1/8
Answer:
use formula of equilateral triangle = roots 3/4 a square.
Fill in the values and calculate:
1/4 * 6 + 3*7 = 6/4 + 21 = 22 1/2
5; 5,000 to 10,000
................................
n = 66
Step-by-step explanation:
you can make a proportion 3/99 = 2/x
99 * 2= 198
3 * x = 3x
so the equation would be 198 = 3x
than do 198 ÷ 3 on ur calculator
so x (or n in this context) would equal 66
