Answer:
1.404
Step-by-step explanation:
Using the rule of logarithms
log x - log y ⇔ log( )
Hence
21 - 3 = ( = 7
Thus
7 = 2.196 - 0.792 = 1.404
You need to find the probability of Heads, Heads, Heads in 3 tosses;
P(HHH)= (1/2)(1/2)(1/2) <-- each toss has 2 possibilities and heads is one
P(HHH)=1/8
Therefore, the probability of flipping 3 heads on a fair coin is 1/8
Hope I helped :)
M+31=6w*
m+w=11**
from *
m=6w-31
sub into **
6w-31+w=11
6w+w=42
7w=42
w=6
Answer:
1/81
Step-by-step explanation:
P(1st ticket is a winner) = 1/9
These are independent events
P(2nd ticket is a winner) = 1/9
P (winner, winner) = 1/9 * 1/9 = 1/81
