Step-by-step explanation:
Alex finally understands how Bob was trying to trick him into winning the bet because of how he puts in the condition for probability being less than 10%. Whichever way the outcome of the coin toss turns out to be, it will be in Bob's favor and Alex will lose the bet. If the coin is flipped 3 times, the probability of having heads exactly twice is 
Step-by-step explanation:
1. solution,
length of rectangle A(l)=3.1units
breadth of rectangle A(b)=1units
now,
area of rectangle A=l×b
=3.1units×1units
=3.1 sq units
2.solution,
length of rectangle B(l)=3.1units
breadth of rectangle B (b)=0.4units
now,
area of rectangleB=l×b
=3.1units×0.4units
=1.24 sq units
3.solution,
length=3.1units
breadth=1.4units
area =lxb
=3.1units x 1.4units
=4.34units

there is nothing to prove
Step-by-step explanation:
Answer:
25%
Step-by-step explanation:
125:500
divide by 5 to make 500 into 100
25:100
convert to percent
25%
Area = area of the square in the center + 2 * area of the 2 quarter circles.
= 5^2 + 2 * 1/4 *3.14 * 5^2
= 25 + 39.25
= 64.3 in^2 answer
