Answer

Explanation:

Step1: Identify frequencies for ages < 30

From the histogram, the frequencies for age - groups 0 - 10, 10 - 20, 20 - 30 are 10, 20, 30 respectively.

Step2: Calculate total frequency

Sum up all the frequencies in the histogram. Let's assume the sum of all frequencies (n) is the total number of data - points. By adding all the bar - heights: (n=10 + 20+30 + 40+30+20+10+5+5 = 170).

Step3: Calculate sum of frequencies for ages < 30

The sum of frequencies for ages less than 30 is (10 + 20+30=60).

Step4: Calculate the percentage

The percentage (P) of deaths of individuals younger than 30 is given by the formula (P=\frac{\text{Frequency of ages}<30}{\text{Total frequency}}\times100). Substitute the values: (P = \frac{60}{170}\times100=\frac{6000}{170}\approx35.3).

Answer:

35.3%
