If the odds against Deborahs winning first prize in a chess tournament are 1 to 11 what is the probability of the event that she

Lemur [1.5K]

Answer: $\dfrac{11}{12}$

Step-by-step explanation:

Given

The odds against winning in a chess tournament are 1 to 11.

Odds is defined as the ratio of the probability of occurrence to the non-occurrence of event.

$\therefore \text{Probability that event will occur is P'=}\dfrac{1}{1+11}\\\\\Rightarrow P'=\dfrac{1}{12}$

Probability of non-occurrence i.e. she wins the first prize is

$\Rightarrow P=1-\dfrac{1}{12}\\\\\Rightarrow P=\dfrac{11}{12}$

In 2004, it was reported that "the relationship between body mass, M, and standard metabolic rate, B, among living organisms rem

lesya692 [45]

The answer is 8884.37 times

In many cases, B is approximately proportional to the three-quarters power of M:
 $B= M^{3/4}$

Elephant:
M1 = 4.6 mt = 4.6 * 1,000,000 g = 4,600,000 g
 $B1= 4600000^{3/4}=99327.24$

Mouse
M2 = 25 g
$B2= 25^{3/4}=11.18$

determine how many times greater the metabolic rate of an elephant is than that of a mouse:
B1/B2 = 99327.24 / 11.18 = 8884.37 times
