Is this number written in scientific notation 4.8•100^7

1 answer:

3 0

No this number is not written in scientific notation
In scientific notation, it'll look like
4.8 * 10 ^14

In scientific notation it's 10 ^ n
NOT 100^n

Hope this helps

The probability of winning on a single toss of the dice is p. A starts, and if he fails, he passes the dice to B, who then attem

alekssr [168]

Answer:

The probability of A winning is $\frac{1}{2-p}$ and the probability of B winning is $\frac{1-p}{2-p}$ .

Step-by-step explanation:

The probability of winning is p.

The game stops when either A or B wins.

The sample space of A winning is as follows:

{S, FFS, FFFFS, FFFFFFS, ...}

The sample space of B winning is as follows:

{FS, FFFS, FFFFFS, FFFFFFFS, ...}

Compute the probability of A winning as follows:

P (A winning) = P (S) + P (FFS) + P (FFFFS) + ...

$=p+(1-p)(1-p)p+(1-p)(1-p)(1-p)(1-p)p+...\\=p\sum\limits^{\infty}_{i=0} {(1-p)^{2i}}\\=p\times \frac{1}{1-(1-p)^{2}}\\=\frac{p}{1-(1-p)^{2}}\\=\frac{p}{1-1-p^{2}+2p}\\=\frac{1}{2-p}$

Compute the probability of B winning as follows:

P (B winning) = P (FS) + P (FFFS) + P (FFFFFS) + ...

$=(1-p)p+(1-p)(1-p)(1-p)p+(1-p)(1-p)(1-p)(1-p)(1-p)p+...\\=(1-p)p\sum\limits^{\infty}_{i=0} {(1-p)^{2i}}\\=(1-p)p\times \frac{1}{1-(1-p)^{2}}\\=\frac{(1-p)p}{1-(1-p)^{2}}\\=\frac{(1-p)p}{1-1-p^{2}+2p}\\=\frac{1-p}{2-p}$

Thus, the probability of A winning is $\frac{1}{2-p}$ and the probability of B winning is $\frac{1-p}{2-p}$ .

How many cookies could you make with four cups of flour

lina2011 [118]

Hi there!

Usually, the amount of flour varies between different cookie recipe's, but if you're going to make the normal chocolate chip cookie, into a batch of 60, you'd need 4 cups of flour.

So, 4 cups of flour would make your 60 chocolate chip cookies.

Hope this helps! :D
