पर्याय
`1/13 xx 1/13`
`1/13 xx 1/13`
`1/13 xx 1/17`
`1/13 xx 4/51`
उत्तर
Two cards are drawn from a well-shuffled deck of 52 playing cards with replacement. The probability, that both cards are queens, is `1/13 xx 1/13`.
Explanation:
Probability of getting Queen = `4/52`
So, the required probability
= P(Queen).P(Queen)
= `4/52*4/52`
= `1/13*1/13` ....(With replacement)

Read the following passage and answer the questions given below:
In an Office three employees Jayant, Sonia and Oliver process incoming copies of a certain form. Jayant processes 50% of the forms, Sonia processes 20% and Oliver the remaining 30% of the forms. Jayant has an error rate of 0.06, Sonia has an error rate of 0.04 and Oliver has an error rate of 0.03. |
Based on the above information, answer the following questions.
- Find the probability that Sonia processed the form and committed an error.
- Find the total probability of committing an error in processing the form.
- The manager of the Company wants to do a quality check. During inspection, he selects a form at random from the days output of processed form. If the form selected at random has an error, find the probability that the form is not processed by Jayant.
