tekilochka [14]
Subtracts 150 each time—


950-150=800 and 800-150=650 and so on and so forth. The number sequence only includes 5 numbers so there is no way to tell if there is a tougher solution.

Flip 10000 fair coins. You are offered a 1-1 bet that the sum is less than 5000. You can bet 1, 2, ..., 100 dollars. How much wi
insens350 [35]

Answer:

Step-by-step explanation:

Given that 10000 times a fair coin is flipped. Since fair coin prob for head of tail =0.5

If tail comes it will be taken as 1.  Hence for the sum to be less than 5000, no of heads <5000

Since trials are large we approximate to normal with mean = np = 5000 and variance = np(1-p) = 2500

Thus no of heads x is normal with (5000, 50)

P(X

Since this prob is less than 0.5 only minimum amount to be bet i.e. 1 dollar

If sum of coins <5100, then Z = \frac{5100-5000}{50} =2

P(Z<2) = 0.9500

This time we can bet maximum of 100 dollars as probability is very high nearer to 1.
