A die is thrown 10 times, the probability that an odd number will come up at least one time is
Options
- A1 1024
- B1023 1024
- C11 1024
- D1013 1024
Correct answer
B. 1023 1024
Step-by-step solution
A die is thrown 10 times Probability of success is an odd number n=10, p= 1 2 , q= 1 2 Number of success is atleast one Required probability P(x 1)=1-P(x=0)=1- 10 0 ( 1 2 )⁰ ( 1 2 )¹⁰=1- 1 1024 = 1023 1024
