A coin is tossed on two successive times. I) Write the sample space ii) P( getting exactly one head) iii) P( getting no heads) iv) P( getting at least one tail) SECTION C : Question 21 – 30 carry 3 marks

Given : A coin is tossed two times successively.

Solution:

Formula used: Probability =

(i) Sample space

(ii) P( getting exactly one head) =

(iii) P( getting no heads)=

(iv)P( getting at least one tail)=

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
