A fair coin is tossed three times and the events A, B, and C are defined as follows: A:{ At least one head is observed } B:{ At

kicyunya [14]

Answer:

(a) 1/2

(b) 1/2

(c) 1/8

Step-by-step explanation:

Since, when a fair coin is tossed three times,

The the total number of possible outcomes

n(S) = 2 × 2 × 2

= 8 { HHH, HHT, HTH, THH, HTT, THT, TTH, TTT },

Here, B : { At least two heads are observed } ,

⇒ B = {HHH, HHT, HTH, THH},

⇒ n(B) = 4,

Since,

$\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

(a) So, the probability of B,

$P(B) =\frac{n(B)}{n(S)}=\frac{4}{8}=\frac{1}{2}$

(b) A : { At least one head is observed },

⇒ A = {HHH, HHT, HTH, THH, HTT, THT, TTH},

∵ A ∩ B = {HHH, HHT, HTH, THH},

n(A∩ B) = 4,

$\implies P(A\cap B) = \frac{n(A\cap B)}{n(S)} = \frac{4}{8}=\frac{1}{2}$

(c) C: { The number of heads observed is odd },

⇒ C = { HHH, HTT, THT, TTH},

∵ A ∩ B ∩ C = {HHH},

⇒ n(A ∩ B ∩ C) = 1,

$\implies P(A\cap B\cap C)=\frac{1}{8}$

H/2 + 21 - k if h=20 and k=89

Hoochie [10]

$\huge\text{Hey there!}$

$\mathsf{\dfrac{h}{2} + 21 - k\ if\ h=20\ and\ k=89}$

$\textsf{If h = 20 and k = 89, the SUBSTITUTE it for where they are in the equation}$

$\mathsf{\dfrac{10}{2}+21 - 89}$

$\mathsf{\dfrac{20}{2}= \bf 10}$

$\mathsf{\bold{10}+21 - 89}$

$\mathsf{10+21=\bf 31}$

$\mathsf{\bold{31}-89= \underline{ANSWER}}$

$\mathsf{= \bf -58}$

$\boxed{\boxed{\large\text{Answer: \huge \bf -58}}}\huge\checkmark$
