Answer
ways
the coin can land tails either exactly 8 times or exactly 5 times in
ways
Step by step explanation:
THis is a binomial distribution
Binomial distribution gives summary of the number of trials as well as observations as each trial has the same probability of attaining one particular value.
P(9)=(14,9).(0.5)⁹.(0.5)¹⁴⁻⁹
p(3)=(14,3).(0.5)⁹.(0.5)¹⁴⁻³
p=(9)+p(3)
p=C(14,9)(0.5)¹⁴ + C(14,3). (0.5)¹⁴
P= (0.5)¹⁴ [C(14,9) + C(14,3)]
P= (0.5)¹⁴ [2002 * 364]
P= 1/16384 * (2002 +364)
P= 91091/2048
P= 0.144
Hence,the coin can land tails either exactly 8 times or exactly 5 times in
ways
Answer:
a:b = 11:3 and a:b:c = 11:3:2
Step-by-step explanation:
a:b is equal than write a/b. So a/b=11/3 it means a:b = 11:3
b:c is then b/c = 2
For a:b:c the ratio must be maintained. Ratio is equals reasons or divides. We already know a:b is 11:3. What about a:c?
3a=11b then a=11/3 b, b=2c then c=1/2 b hence a/c =22/3 if we pay attention this reason is 2*11/3 so a:b:c is 11:3:2
15/45 all you have to do is simplify each number to get your answer
