50
Step-by-step explanation:
lxb=144
16xb=144
b=9
perimeter=2(l+b)
=2(16+9)
=50 cm
Step-by-step explanation: The standard formula for geometric sequence is an = a1 * r^(n-1) where r is the geometric factor and n is an integer. In this problem, upon substitution, an = 4*2^(n-1).
Your expected win from this bet would be about -0.05, meaning that you can expect to lose 5 cents on each $1 bet.
To find this we multiply the probability for each bet times $1. Remember in Roulette, there are 18 red, 18 black and 2 zero spaces.
(18/38) x 1 + (20/38) x -1 = -0.05
