Detailed Solution

Given, a dice is thrown 400 times.
Sum of frequencies

n (S) = 400

Odd numbers are

1, 3, 5

.
Therefore, frequency of all odd numbers

n (E) = 70 + 60 + 63 = 193

P (E) = \frac{n (E)}{n (S)}

P (E) = \frac{193}{400}

Thus, probability of occurrence of odd number

= \frac{193}{400}

Therefore, option (3) is correct.
