Answer:
0.25
Step-by-step explanation:
Prime outcomes on a die: 2,3,5
P(prime) = 3/6 = 1/2
Even outcom: 2,4,6
P(even) = 3/6 = 1/2
P(prime & even)
= P(prime) × P(even)
= ½ × ½
= ¼ or 0.25
 
        
             
        
        
        
<span>here we can use Pythogoras' theorem. 
in right angled triangles the square of the hypotenuse is equal to the sum of the squares of the other 2 sides. 
hypotenuse is 19 cm. One side is 13 cm and we need to find the length of the third side. 
                                                                          
19</span>²<span> = 13</span>²<span> + X</span>²<span> 
X - length of the third side 
                                                           
361 = 169 + X</span>²<span> 
X</span>²<span> = 361 - 169 
                                                                     
X</span>²<span> = 192 
                                                                              
X = 13.85 the length of third side rounded off to the nearest tenth is 13.9 cm</span>
