An insurance company found that 45% of all insurance policies are terminated before their maturity date. Assume that 10 polices are randomly selected from the company’s policy database. Assume a Binomial experiment.
Required:
a) What is the probability that eight policies are terminated before maturity?
b) What is the probability that at least eight policies are terminated before maturity?
c) What is the probability that at most eight policies are not terminated before maturity?
A sample of pure diamond was burned in pure oxygen, formed carbon dioxide was collected, and then bubbled through 3.50 L of 0.437 M sodium hydroxide solution. Bubbled carbon dioxide
was converted to sodium carbonate by the reaction shown below.
CO2(a) + NaOH,da) > Na) COgag) + H200)
After the reaction remaining, NaH was determined by back titration with 0.350 M HI solution,
and 1.71 L of the titrant was consumed for neutralization of the leftover NaH. What volume of
oxygen gas was consumed in the process if it was measured at 7.6 atm and 20 °C?
Calculate q, w, and AE for the vaporization of 25.0 g of liquid ethanol (C¿H; OH) at 1.00 atm
at 78.0 °C, to form gaseous ethanol at 1.00 atm at 78.0 °C. The density of liquid ethanol at 78.0
°C is 0.789 g/mL, and the heat of vaporization of ethanol is 855 J/g.

Research has shown that 55% of new Small Medium Enterprises (SMEs) are started by graduates while 45% are started by non-graduates. It is also known that 70% of SMEs started by graduates are successful i.e. they survive beyond 3 years, while only 10% of those started by non-graduates are successful.
Required:
a) What is the probability that a new SME is successful?

the probability of winning is 1/3. Mona plays 6 games. Find probability of winning exactly 5 games.
if you were to flip a coin 20 times what is the probability you wpuld get exactly 10 heads
. A helium-filled balloon rises until its density becomes the
same as that of the surrounding air. If a sealed submarine
begins to sink, will it go all the way to the bottom of the
ocean or will it stop when its density becomes the same as
that of the surrounding water?
A 59yr old man, Koosei was admitted unconscious to the emergency room from a local bar days after DNA tests revealed he was not the biological father of his 6 children. The bartender revealed that he is able to eat only a half-ball of kenkey and black pepper and drinks lots of Oyaw Bitters.
